A prerequisite for a meaningful assessment of component durability and life is the ability to accurately predict the stress and strains occurring within a loaded structure composed of a given material. As constitutive material models provide the required link between stress and strain, this by necessity demands the development and characterization of an appropriate constitutive behavior model for any new material before a designer can certify that material for use.
In view of more than three decades of active research in the area of inelastic behavior modeling, the need still exists for an accurate representation of material response details over an extensive domain of time, stress, temperature, and loading conditions. COMPARE, the COnstitutive Material PARameter Estimator, enables the engineer to characterize material models for use in finite element analysis.
