Fatigue and Quasi-static Crack Growth Analysis : Thermoelasticity Module

The Boundary Element Method (BEM) is now widely regarded as the most accurate numerical tool for the analysis of crack problems in linear elastic fracture mechanics.

This "crack growth" software utilizes the BEM and and removes the task of remeshing as the crack propagates, which is one of the drawbacks of finite element software.

Furthermore, it evaluates accurate stress intensity factors for which the BEM is renowned.

The software uses the established criterion for crack propagation and evaluates residual strength as well as fatigue life calculations.

In addition to the basic crack growth analysis capabilities of the standard code, this module permits the solution of problems subjected to thermal loadings.

The thermoelastic code utilizes the J-integral technique to evaluate stress intensity factors for mixed-mode crack problems and can be used for problems with thermal and/or mechanical loading conditions for cracked and uncracked problems.

The code will also evaluate temperatures or flux and displacement or stresses at boundary or internal points.

The module can be used to simulate crack growth due to combined thermal and fatigue loadings.
