摘要： PROBLEM TO BE SOLVED: To simulate an aging effect of a chrono-rheological material (for example, rubber, foam or the like) in computer aided engineering (CAE) analysis.
SOLUTION: According to one aspect, a set of material property tests is conducted for the chrono-rheological material of interest (602). Each test obtains a series of relaxation test data by maintaining a predefined fixed strain of each sample (604). A set of first and second time-dependent material aging effect parameters is determined by shifting and matching the series of relaxation test data between respective pairs out of the plurality of material property tests. Then, an engineering structure in which the one set of the first and second time-dependent material aging effect parameters includes at least partially the chrono-rheological material is carried out CAE-analysis, in cooperation with a CAE analysis application module constituting a chrono-rheological material structural equation (608).

摘要： Methods and systems for enabling simulation of material aging effect of chrono-rheological materials in computer aided engineering (CAE) analysis are disclosed. According to one aspect, a set of material property tests is conducted for a chrono-rheological material of interest. Each test obtains a series of material properties such as relaxation test data at different age. The relaxation test data are measured by maintaining a specimen of the chrono-rheological material at a predetermined strain. A set of first and second time-dependent material aging effect parameters is determined by shifting and matching the series of relaxation test data between each pair of the tests. The set of first and second time-dependent material aging effect parameters in conjunction with a CAE analysis application module with a chrono-rheological material constitutive equation configured therein are then used for simulating material aging effect by performing a CAE analysis of an engineering structure containing at least in part the chrono-rheological material.

摘要： PROBLEM TO BE SOLVED: To enable the extremely precise simulation of hot carrier deterioration which can be applied to various fields by newly developing a extremely accurate substrate current model and using the model.
SOLUTION: A substrate current Isub is calculated by using the substrate current model expressed by Isub=(Ai/Bi)×(Vds-Vdsat)×Id×exp[-Bi×lc/(Vds-Vdsat)], where Id, Vds, and Vdsat are a drain current, a drain voltage, and a saturation drain voltage of a MOS transistor, lc is a characteristic length, Ai is a model parameter, and Bi is a predetermined constant. In this model, the characteristic length lc is a function (lc=lc[lc0+lc1×Vgd]) of a linear expression (lc0+lc1×Vgd) of a gate-to-drain voltage Vgd(=Vgs-Vds, where Vgs is the gate voltage of the MOS transistor) of the MOS transistor, where lc0 and lc1 are model parameters.
