文摘
- •
Generalized energy-based method for predicting 3-D, non-planar crack growth.
- •
A new global implementation of the virtual crack extension method is used.
- •
A crack-extension function is determined to govern the incremental front evolution.
- •
Methodology reduces numerical bias and the need to prescribe crack advances.
- •
Predicted global non-planar and local front behavior, e.g. factory-roof formation.
