Features tested

User subroutine to define time-dependent behavior for models defined within the parallel rheological framework.

Problem description

The input file consists of two elements with the material response specified using the parallel rheological framework with two networks using the power law strain hardening and hyperbolic-sine creep laws. The same material models are assigned to each element; however, the viscous behavior in the networks is defined in two different ways. In one case user subroutine VUCREEPNETWORK is used to specify the power law strain hardening and hyperbolic-sine creep law. In the second case the built-in Abaqus creep laws are used. The analysis consists of one step, and both elements are subjected to the same load history. The specimens are loaded rapidly at the beginning of the step and the load is maintained throughout the step, so the materials are subjected to creep.

Results and discussion

The results obtained using the two equivalent materials show very good agreement.
