How to run COMSOL Multiphysics using an input file and a command prompt. It is easy using the Java API.
Guide to using MCalibration and PolyUMod with COMSOL Multiphysics. A complete start-to-finish tutorial is presented.
Soft polymer foams, and some other materials, often exhibit different stiffnesses in uniaxial tension and compression. Most material models cannot predict this type of behavior, but there are some excellent choices for this.
A material model is considered Drucker’s stable if an increase in strain results in an increase in stress. In some cases it can be important to enforce that a material model is Drucker’s stable. This article shows how you can easily achieve this in MCalibration.
In this article I will show how you can quickly convert any Ansys material model (in APDL format) into stress-strain predictions using MCalibration. Here are
It is easy to create stress-strain plots for any Abaqus material model using MCalibration. This article shows how.
The Extended Tube model is one of the most accurate hyperelastic material models available, but it can be difficult to use if you don’t understand how the material parameters influence the predicted stress-strain response. This article will demonstrate that by example.
Tutorial showing how to use MCalibration to calibrate the Abaqus Johnson-Cook model with failure to experimental data.
Introduction to how MCalibration and PolyUMod can be used with Altair Radioss. This is a great starting point if you are new to our software.
Resulting is a term used in the book “Thinking in Bets” to describe how not to make decisions when all you have is limited information. In this article I will describe how this relates to material modeling.
Review of some practical differences between linear and non-linear viscoelasticity.
Summary of how you can instantaneously calibrate an Abaqus linear viscolastic material model using DMA data using MCalibration version.
Complete step-by-step tutorial on how to use HyperMesh to setup a Radioss FE model with a PolyUMod material model.
Short tutorial on how to run Radioss with the PolyUMod library from the command line.
Description of how to plot the viscoplastic strain magnitude when using PolyUMod or MCalibration.
Best Abaqus and Ansys material models in 2021 – thermoplastic elastomers
When you work with material models it is always important to think about the type and quality of experimental data that you have. I wrote
