Calibration of a material that softens after yield

Sun, 04 Mar 2012 22:34:00 -0600

Some polymers (e.g. thermoplastics, adhesives) exhibit a reduction in stress after yielding. This behavior can be difficult to capture using a simple material model. This presentation illustrates how MCalibration can be used to create and calibrate a material model (the PNM) from the PolyUMod library that can predict a significant reduction in stress after yield.

MCalibration: How to run a parametric study

Sun, 04 Mar 2012 19:17:00 -0600

When working with an Abaqus, ANSYS, or PolyUMod material model is can be very useful to examine which of the material parameters are most important, and how each material parameter influences the predicted stress-strain response. These tasks are easy to perform using a parametric

MCalibration: How to calibrate any Abaqus material model

Thu, 01 Mar 2012 13:28:00 -0600

This tutorial illustrates how MCalibration can be used to calibrate any of the built-in material models in Abaqus. The approach is based on the "Abaqus-Template" material model framework that is available in MCalibration.

MCalibration: How to activate a failure model
