ENVIRONMENTAL EFFECTS PLUGGED INTO
YOUR APPLIED COMPOSITE MECHANICS

What is CheFEM?
CheFEM quantifies effects of environmental exposure on mechanical response of polymers and their composites. CheFEM is based on fundamental "Chemical" Sanchez-Lacombe Equation of States and "Mechanical" FEM routines. CheFEM can seamlessly handle any liquid/gas exposure of any polymer material based application.
