Abaqus Tutorial 21: Compression & Stress Relaxation of a Viscoelastic Rubber Seal

In this tutorial, you will investigate the time-dependent viscoelastic behaviour of a rubber seal after compression. You will use the Abaqus calibration tool to calibrate a linear viscoelastic material model of a generic rubber starting from stress-relaxation test-data. Quadrangular 2D plane strain elements will be used.

When you complete this tutorial, you will be able to:

• Calibrate a linear viscoelastic material model starting from experimental stress relaxation test data.
• Create a model to compress a rubber seal with a *static procedure and then evaluate its stress relaxation using a *visco procedure.
