GROWTH
GROWTH is the module for Crack Growth analysis in 2D (or quasi-2D) structures.
Topics addressed:
-
FEM remeshing for propagation of multiple cracks
-
Crack stop drill holes
-
Stress Intensity Factors calculated with J-integral, Displacement correlation

QUICK2DFEM
QUICK2DFEM is a module, not optional, integrated by default in LIFING, solving 2D plane stress or plane strain models created by defining edge geometries and conditions with a simple format.
Created models can be used for both Fatigue and Crack Growth assessments.
