Penn State has been advancing iVABS for design-to-production of composite rotorcraft blades. The university is incorporating manufacturing constraints into the design process to enable more realistic blades.

Penn State has been using AnalySwift’s VABS simulation software as well as the open source iVABS tool to improve the manufacturability of composite rotor blades used for helicopters, air mobility, and other rotorcraft. The work is part of the Penn State Vertical Lift Research Center of Excellence (VLRCOE), a premier research and education hub at Penn State dedicated to advancing vertical lift technologies—such as helicopters, drones, and VTOL systems—in key areas like aeromechanics, flight dynamics, propulsion, acoustics, and survivability.

This work has been done under AnalySwift's Academic Partner Program (APP), which offers participating universities no-cost licenses of engineering software programs VABS and SwiftComp so students, researchers, and faculty can leverage the tools in their academic research.

“The optimization of rotor blade design plays a critical role in improving overall rotorcraft performance,” said Jiwoo Song, who is pursuing a PhD degree in aerospace engineering at Penn State. “Recent advancements in computational toolchains, such as iVABS, enable rapid exploration of design spaces while satisfying prescribed performance objectives. The goal of the project is to achieve a design-to-production capability by developing a drastically more manufacturing-aware iVABS blade design framework. Looking ahead, this project aims to move beyond virtual optimization into physical realization, with plans to fabricate a composite rotor blade in collaboration with the Penn State Applied Research Laboratory, validating the computational design process through experimental testing.”

CompositesAI was one of 33 finalists in JEC Composites Innovation Award competition.

AnalySwift congratulates all the teams who made the finals list for the 2026 JEC Composites Innovation Award. The company is excited to have its CompositesAI selected as one of the 33 finalists in 11 categories. We extend our thanks to JEC and the jury for this recognition. CompositesAI, a platform jointly developed by AnalySwift and Purdue University, was selected as one of three finalists in the Digital, AI & Data category. Created in 1998, the JEC Composites Innovation Award program aims to identify, promote, and reward the most innovative composite solutions worldwide.

CompositesAI is an AI-powered expert system that consolidates certified composites knowledge and simulation tools via LLMs. It combines the authority of leading experts with the precision of simulation software, enabling domain experts to build custom AI agents without AI expertise.

"Advanced composites enable lighter, high-performance structures, but decades of accumulated knowledge remain fragmented across documents, software tools, and experts’ tacit experience," said Dr. Wenbin Yu, AnalySwift CTO and the Milton Clauser Professor of Aeronautics and Astronautics at Purdue University. "CompositesAI addresses this by creating an AI-powered expert system that unifies static data (papers, standards, reports), dynamic data (simulation tools, physics-based or machine-learned), and tacit engineering insight. The platform provides sourced, explainable, traceable answers to natural-language queries, while linking prompts directly to physics-based or machine-learning simulations. The growing corpus will support a composites-specific foundational model."

Key benefits of CompositesAI:
- Consolidate all composites expert knowledge
- Democratize expert knowledge using chat interface
- Enable simulation tools for entire supply chain
- Leverage all public composites knowledge and tools
- Intelligentize proprietary knowledge via AI

AnalySwift CTO, Dr. Wenbin Yu, has published a book introducing his new, top down approach to multiscale structural mechanics.

Dr. Yu, AnalySwift CTO and Milton Clauser Professor of Aeronautics and Astronautics at Purdue University, has published a new book, Multiscale Structural Mechanics: Top-Down Modeling of Composite Structures Using Mechanics of Structure Genome with Wiley (January 2026). The book represents a practical, unified approach to multiscale composites modeling—bridging micromechanics and structural mechanics with clarity and rigor.

This unified and rigorous approach to modeling composite structures is grounded in the concept of the Structure Genome. It integrates micromechanics and structural mechanics through the Mechanics of Structure Genome (MSG), enabling multiscale constitutive modeling for general anisotropic and heterogeneous materials—without relying on the limiting assumptions found in traditional methods.

The book introduces readers unfamiliar with vectors and tensors, continuum mechanics, micromechanics, and structural mechanics to the basics of each of these topics. It goes on to bridge the gap between micromechanics and structural mechanics, offering readers multiscale structural models that remain as simple as classical engineering models but with the accuracy expected of more complex theories capturing microstructural details.

Designed for both newcomers and experienced practitioners, the book covers:
- A concise intro to vectors, tensors, continuum mechanics, and classical structural models
- In-depth discussion on MSG and its application to beams, plates, shells, and 3D solids
-A full bridge between micromechanics and structural mechanics
- Use of calculus of variations and variational asymptotic methods for composite modeling
- Guidance to construct efficient, high-fidelity composite models
- Insights on stress and failure analysis of composite laminates

Whether you’re a graduate student in aerospace or mechanical engineering, or a researcher/engineer working with composite materials, this book is a powerful resource for modeling complex structures with engineering-level simplicity and precision.

Links to get the book to explore how multiscale thinking is reshaping composite structures are found in the article. It can be ordered on Amazon, Wiley, and Amazon Canada. Signed copies of the book will additionally be available for purchase at the ASME SSDM Conference June 8-10 2026, in Long Beach, California. AnalySwift is a Platinum Sponsor of ASME’s 4th Annual Aerospace Structures, Structural Dynamics, and Materials Conference (SSDM).

A new publication on fatigue delamination in composites by AnalySwift and collaborators is now available.

AnalySwift is excited to share the latest journal paper by Senior Research Scientist Dr. Liang Zhang and collaborators on machine learning–aided cohesive zone modeling (CZM) for fatigue delamination. The paper was published in the Mechanics of Advanced Materials and Structures on January 18, 2026.

"The proposed CZM accurately captures high-cycle, mixed-mode fatigue delamination and can be directly calibrated from experimental G–N and crack growth rate data," said Dr. Zhang. "By integrating machine-learning surrogates into the calibration workflow, the approach reduces the required number of full finite-element simulations by about 90%, delivering major efficiency gains while maintaining accuracy."

"These advancements are particularly relevant to industries and applications involving composite durability and fatigue life prediction, including aerospace structures, defense systems, automotive composites, wind energy, and other high-performance composite applications," continued Dr. Zhang.

This is is part of work being done in the Active Aeroelasticity and Rotorcraft Laboratory (AARL) in the Department of Aerospace Engineering at Seoul National University and SNU-UAM Center, a research center dedicated to developing the core technologies for urban air mobility (UAM).

“SNU-UAM Center brings together 12 laboratories from 7 universities, including Seoul National University, with the goal of securing the core technologies for Urban Air Mobility (UAM),” said Professor SangJoon Shin of the Department of Aerospace Engineering at Seoul National University.

“To ensure the safe operation of UAM vehicle, it will be essential to avoid the ground resonance, and VABS enables us to design the rotor blade cross section that avoids resonance within the operational frequency range. We have been using VABS program to perform cross-sectional design based on the given geometries and to achieve the desired vibration characteristics for the rotor blades integrated with a gimballed hub,” Professor Shin explained. “First, we designed the blade cross section and used VABS to obtain the corresponding stiffness matrix. Then, we provided this result into CAMRAD II, a performance analysis program for a rotorcraft, to compute the vibratory response under the realistic flight condition.”
