Numerical Simulation of Crack Growth [PDF]
PAMM, 2006 AbstractIn recent years the X‐FEM based on the partition of unity method and the strong discontinuity approach (SDA) have shown to be powerful tools to model crack growth. Both methods model the crack surface by introducing additional d.o.f.. In the X‐FEM the nodes in the mesh around a crack are globally enhanced with new d.o.f. while in in the SDA the

Crack growth simulation in heterogeneous material by S-FEM and comparison with experiments [PDF]
Fracture and Structural Integrity, 2015 Fully automatic fatigue crack growth simulation system is developed using S-version FEM (SFEM). This system is extended to fracture in heterogeneous material. In the heterogeneous material, crack tip stress field becomes mixed mode condition, and crack
