VIRTUAL ANALYSIS OF ENVIRONMENTAL EFFECTS
ON MECHANICAL RESPONSE AND PERMEATION

What is CheFEM?
CheFEM quantifies effects of chemical-thermal exposure on mechanical response and permeation (emission) characteristics. CheFEM simulation is based on enhanced "Chemical" Sanchez-Lacombe Equation of State and "Mechanical" FEM routines. This unique approach allows users to perform quick assessments of different materials and to virtually reformulate polymer chemistry and filler composition of materials.
