Temperature Testing for Material Model Calibration
In this article I will explain what types of experiments are needed in order to calibrate a temperature-dependent material model.
In this article I will explain what types of experiments are needed in order to calibrate a temperature-dependent material model.
This article examines different material models for polyetherimide (PEI), and finds the most accurate model for FEA use.
It commonly believed that the stress concentration factor for a plate with a hole in uniaxial tension is 3. This not true!
When performing uniaxial tests, you should consider also recording the transverse strain. This article shows how use the transverse strain data.
This article explains how you can know if a material is linear or non-linear viscoelastic. A few simple tests are all that is needed.
Crack driving forces extend the J-integral and allow for analysis of the fracture response of viscoplastic materials under any load history.
This article shows how you can use the new Master Curve tool in MCalibration to quickly generate a TTS master curve from experimental data.
This article discusses how to experimentally measure the J-integral using basic tension experiments and specialized specimen geometries.
The J-Integral is the key quantity of Elastic-Plastic Fracture Mechanics (EPFM). This article shows how to derive it from first principles.
