What is CRACK3D?
CRACK3D is a finite-element-based software tool for three-dimensional (3D) crack growth simulation that I have been developing since I joined Profs Sutton and Deng's research team at University of South Carolina in Jan. 2001. The first version was released in Aug. 2001. After 7-year research and development, CRACK3D currently has many unique features that are fully functional for predicting 3D crack growth under general deformation conditions.
CRACK3D has been funded by NASA, AFRL, USAF and GM, which require to develop a computational methodology and 3D ductile fracture criterion to be used for numerically predicting structural fracture behavior and maximum residual strength that are critical concerns in practical engineering designs.
How does it work?
CRACK3D is a stand-alone 3D fracture mechanics simulation code, as shown in Figure 1. It is not tied to a particular commercial software even though interfaces between CRACK3D and commercial codes have been provided.

CRACK3D provides a state-of-the-art capability for modeling 3D crack propagation in engineering structures with complex topology. It can be applied in many industries in which knowledge of crack behavior, maximum load-carrying capacity, fracture path prediction, residual strength and predictive risk analysis of structures are important issues, e.g.
nuclear, chemical and oil industries
CRACK3D aims at reliability and safety analysis of engineering structures. It can benefit customers in many aspects.
Time critical decision making (e.g. whether the mission has to be cancelled or not?)
Numerically testing and predicting failure mode of products
Improving design by reconstruction and visualization of failure process
Maximizing product safety and reliability at the earliest stage
Predictive risk analysis to avoid occurrence of tragedies
