Computational Methods and Their Applications in Composite Materials: Multiscale and Multiphysics Modeling

Composite materials typically consist of two or more distinct constituents, each with its own properties and behavior. They have been widely utilized in aerospace, automotive, marine, and civil engineering applications. Traditional experimental approaches often struggle to capture the intricate interactions occurring at different length and time scales. Computational methods offer a powerful alternative, enabling the simulation and prediction of the complex behavior of composite materials across multiple scales and under various environmental conditions. By integrating models at the macroscopic, mesoscopic, and microscopic levels, multiscale simulations yield valuable insights into the mechanical strength, failure mechanisms, and durability of composites. Moreover, multiphysics modeling approaches are essential for evaluating the coupled effects of moisture (hygro-), temperature (thermo-), and mechanical loading (mechanical) on the performance of composite materials. This presentation will introduce several advanced computational techniques tailored to model the physical responses of composite materials at different scales, with the aim of enhancing the understanding of their deformation and failure mechanisms. These techniques will serve as a foundation and reference for further advancements in the design, optimization, and application of novel composite materials.
