Seminar – Dr. Mauricio Ponga: Mechanics of Materials Across Time, Length and Composition Scales

Mechanics of Materials Across Time, Length and Composition Scales

Speaker: Dr. Mauricio Ponga, Assistant Professor UBC Mechanical Engineering

Principle Investigator at Modeling and Simulation Research Group.

Dr. Ponga will present his research on understanding the mechanics of materials at the nanoscale.

Location: CEME Building (6250 Applied Science Lane), room 1203


Abstract:

In this presentation, I will describe the activities of my research program at MECH, which is focused on understanding the mechanics of materials at the nanoscale. In particular, I will explain how studying subtle nanoscale mechanisms and interactions between atoms and molecules can help us to understand, predict, and ultimately control the mechanisms and properties of materials at the macroscale. My group applies this knowledge in a broad spectrum of applications, including mechanisms of deformation of materials under extreme conditions, to elucidate subtle microstructural features arising from manufacturing processes, develop materials with extraordinary mechanical performance, and understand the binding of viruses to cells and antibodies. I will show how understanding the nano-to-macro linking behavior requires a description of materials across multiple time, length and composition scales, posing several mathematical, modeling and computational challenges. Therefore, my group often develops atomistic tools to extend the realm of molecular simulations, use continuum mechanics models and simulations, and first-principles tools to understand the chemical complexity of materials. The presentation will focus on some of my group’s efforts in this area, showcasing the most important research topics in my portfolio.
