4. B modeling

4.1. Characteristics of modeling

This modeling is identical to modeling A, but with material coefficients defined as functions (constants) of temperature, and the use of an elastic matrix instead of the tangent matrix.

4.2. Tested sizes and results

4.3. notes

The precision of the results is of the same order as for modeling A with an elastic tangent matrix and a smaller redistribution of the time step for the local integration of the model equations.
