On this episode I am speaking to Wenbin Yu, who is a professor at the School of Aeronautics and Astronautics of Purdue University and CTO of AnalySwift, a provider of simulation software for composites. Wenbin 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 modelling of materials and structures, a topic that we delve into 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. In this episode, Prof. Yu and I talk about: 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.
