Abstract:
1. A method of enabling simulation of material aging effects in a computer aided engineering (CAE) analysis, the method comprising: conducting a plurality of identical material property tests for respective specimens of a particular chrono-rheological material, each of the specimens having been aged to a different age and each of the tests being configured to obtain a series of relaxation test data of a corresponding one of the specimens, wherein each of the series of relaxation test data is measured by maintaining the corresponding specimen at a predetermined displacement or strain; determining a set of first and second time-dependent material aging effect parameters that correlates the series of relaxation test data of a pair of the specimens; and configuring a CAE analysis application module such that the material aging effects can be represented numerically with a chrono-rheological material constitutive equation having the set of first and second time-dependent material aging effect parameters included therein, the CAE analysis application module is used for performing a CAE analysis of an engineering structure that contains at least in part the chrono-rheological material, wherein the CAE analysis is used for assisting a user to make decision in improving design of the engineering structure.
