Unmatched Significance
CheFEM's Exposure Thermodynamics is based on calibrated Sanchez-Lacombe Equation of State and William-Landel-Ferry (Free Volume) based shift functions. CheFEM Mechanics is built on validated Micro- & Macromechanical routines. On this basis, material's permeation and mechanical response is determined in any condition.
