How Important is the Bulk Modulus?

Investigation of how important the bulk modulus is in a FE simulation. Using MCalibration and Abaqus, I show that most of the time the bulk modulus has virtually no influence on the FE results.

Calibrate Any COMSOL Multiphysics Material Model using MCalibration

MCalibration can calibrate all solid mechanics material models in COMSOL Multiphysics. This tutorial shows how.

COMSOL: How to Calibrate the Extended Tube Model

Demonstration of how you can quickly calibrate the Extended Tube Model that is available in COMSOL Multiphysics.

Why the Preload Time in a Stress Relaxation Test is Super Important

The preload time is important when you analyze a stress relaxation experiment. This article explains why.

Convert Stress Relaxation Data to a Master Curve and a Linear Viscoelastic Model

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.

Quickly Extract Data from an Image to a Data File

Tutorial on how to extract the data from an image of a graph into either an external data file or MCalibration. The data extraction allows for the use of cubic splines.

Best Material Model for Polycarbonate at High and Low Strain Rates

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.
