Fracture mechanics simulation entails highly advanced and robust modeling of complex cracking problems.  This approach removes many of the simplistic assumptions that are typical of standard fracture mechanics assessments. Quest Reliability’s level of expertise in advanced simulation of cracking and fracture is unrivaled.

The centerpiece of our fracture mechanics simulation tools is FEACrack™, which creates realistic 3D models of components with cracks.  FEACrack can model both stationary and growing cracks and can simulate various crack propagation mechanisms, including fatigue and ductile tearing.

In many fracture assessments, weld residual stresses play an important role.  Quest Reliability has substantial experience and expertise with finite element simulation of welding.  Residual stresses determined from finite element simulation can be mapped onto another model that contains a crack.  This enables an accurate computation of the effect of weld residual stresses on cracking behavior.
