Crack growth simulation of bone under three points bending in Abaqus

In this tutorial crack growth simulation of bone under three points bending in Abaqus has been studied. Structural analysis of bones is now actively studied by many researchers using the finite-element method (FEM) to better understand the mechanism of bone fractures. Most previous studies, however, only obtained distribution patterns of stress or ...

Simulation crack growth in the Koyna dam under seismic load in Abaqus

In this example we consider an analysis of the Koyna dam, which was subjected to an earthquake of magnitude 6.5 on the Richter scale on December 11, 1967. The example illustrates a typical application of the concrete damage base on traction separation laws. Dam is modeled as two dimensional part ...
