The Aerospace Engineering Podcast Interviews AnalySwift CTO on Multiscale Modeling of Composites
AnalySwift is excited to be partnering with the Aerospace Engineering Podcast, where Rainer Groh highlights exciting developments in aerospace engineering. More than 15,000 people visited the Aerospace Engineering Blog each month to learn something new about aerospace engineering. Rainer Groh, research fellow of the Royal Academy of Engineering, has conversations with aerospace pioneers about new technologies on the cutting edge of aerospace design and research. On the most recent episode Rainer interviews Dr. Wenbin Yu, AnalySwift CTO, about Mechanics of Structure Genome the theory that underlies the powerful SwiftComp composite simulation software.
Dr. Wenbin Yu is also a professor at the School of Aeronautics and Astronautics at Purdue University. Dr. Yu has achieved many accolades in both the academic world and in the private sector, and is a fellow of the American Society of Mechanical Engineers. His specialty lies in multi-scale modeling of materials and structures, a topic explored throughout this episode. Material scientists are increasingly inventing materials that are designed from the ground up. This means they take some fundamental building block and then attempt to arrange this building block in an architected manner over multiple length scales.
The challenge with these multi-scale architected materials is that the global macro-scale behaviour is influenced by what happens at the micro-scale. And equally, macro-scale deformations can cause damage at the micro-scale. Therefore, modern computational models that are used to design aircraft need to account for what happens at these different length-scales. Traditionally, this is done by constructing different models for each of the length scales, but the problem with these approaches is that they are computationally inefficient. To overcome this, Prof. Yu has developed the Structure Genome, which allows engineers to efficiently aggregate information of the smaller length scales into models at the greater length scales. This episode includes discussion on the following topics:
- the fundamental difference between a material and a structure
- why multi-scale modelling is important for modern materials and structures
- the Structure Genome
- and how it is being applied to aircraft structures
