Claim One:
1. A method of enabling simulation of material aging effect in a computer aided engineering (CAE) analysis, the method comprising: conducting a plurality of material property tests for a chrono-rheological material, each of the tests is configured to obtain a series of relaxation test data of the chrono-rheological material at different ages, wherein each of the series of relaxation test data is measured by maintaining a specimen of the chrono-rheological material at a predetermined displacement or strain; determining a set of first and second time-dependent material aging effect parameters by correlating the series of relaxation test data of each pair of the plurality of material property tests; and configuring a CAE analysis application module such that the material aging effect 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.
