It would be very handy if uniaxial compression was the same as biaxial tension. But is it? This article has the answer.
MCalibration can calibrate all solid mechanics material models in COMSOL Multiphysics. This tutorial shows how.
The preload time is important when you analyze a stress relaxation experiment. This article explains why.
Tutorial showing how you can take experimentally stress relaxation data at different temperatures and create both a master curve and a linear viscoelastic material model that captures all the data.
Theory of how the constitutive elements influence the predicted yield stress dependence on strain rate
Review of how different material models can be used to predict the non-linear response of PC. Also covers how the yield stress depends on the strain rate.
Quick discussion about the math behind stress relaxation and creep in polymers.
Discussion about how to extrapolate the stress relaxation response of rubbers to long times.
Discussion about how to best estimate the long-term stress relaxation response of a thermoplastic based on short-term data.
Tutorial on how and when to set the ORIENT flag with using Abaqus and an anisotropic material model from the PolyUMod material model.
In this video I will show have to make most Abaqus/Standard simulations that use the PolyUMod library run faster (and with larger time increments). The key is to set an
Demonstration of how to accurately predict the deformation response of a soda bottle under internal pressure.
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
Introduction In this article I will show how you can quickly convert any Ansys material model (in APDL format) into stress-strain predictions using MCalibration. That is, I will show how
