CHEFEM 3: CHEMICAL–MECHANICAL SIMULATOR
Reduce Testing Costs
CheFEM 3 predicts how polymers and composites respond to chemical exposure, including permeation, swelling, stiffness, strength and failure risk.
By applying equations of state to both fluids and the polymer materials themselves, CheFEM 3 connects material thermodynamics with engineering performance—helping reduce testing costs and support service-life predictions.
