Report Introduction:

Composite materials are widely used in modern industries. However, due to the nature of inhomogeneity, analyzing composite structural components poses numerous challenges, such as predicting various sources of damage, e.g., fiber or matrix cracking, interface decohesion and delamination. In addition, various working environments introduce the affection to the mechanical response by other physical fields, like high temperature, oxidation, and moisture. Accordingly, a multiscale combined with multiphysics analysis is essential for the simulation of composite materials. In this presentation, we introduce a multiscale and multiphysics framework in Object-Oriented Fortran (Fortran 2003 or higher) environment named as FOOF (Finite element solver based on Object-Oriented Fortran). A number of simulations for different types of composite materials are demonstrated, including interlayer and intralayer damage simulation for pure mechanical simulation, a concept of computational certification under limited physical experiments, and a coupled mechanical-diffusive-reactive model for a polymer matrix composite (PMC).



About Speaker:
  Dr. Zifeng Yuan received his bachelor's degree from Peking University in 2009. After that, he continued his study at Columbia University under Pro. Jacob Fish’s guidance. And in 2015, he received his Ph. D degree in engineering mechanics. Currently he is doing a postdoctoral fellow at Columbia University.

Dr. Yuan’s research mainly focus on the mechanics methods and software of multiscale calculation for composites, and he had published 7 papers in IJNME, CMAME and some other professional journals.
