MSC.MARC Isotropic ViscoelasticG-912

Description

This TestPak is used to specify the time dependent part of the material behavior of a small strain isotropic viscoelastic material. This TestPak includes measurements of relaxation moduli over a range of temperatures, providing a table of shear modulus vs. time.

Included Tests

1x

M-611

Stress Relaxation/Creep Compliance by Time Sweeps

Options

For the development of an Orthotropic model, contact DatapointLabs.

Samples

: 2 torsional DMA specimen

Application

Data are used in structural analysis simulations to calculate the relaxation of parts with time. The instantaneous moduli for small-strain viscoelasticity are specified using the ISOTROPIC TestPak [G-901]. With this TestPak, only isotropic quantities can be specified.
