LEFM-based simulation of fatigue crack growth under nonproportional mixed-mode loading.
Konferenzveröffentlichung, Bibliographie
Kurzbeschreibung (Abstract)
3-dimensional fatigue crack growth simulation under non-proportional mixed-mode loading is a new and challenging topic in engineering research field. The present paper proposes an algorithm based on linear elastic fracture mechanics to discuss this problem. The crack growth in 4 thin-walled, hollow cylinders with notch under combined non-proportional cyclic tension and torsion are calculated and analysed. Different material, torsion and tension loading ratio MT/F and out-of-phase angle are considered, R ratio equals to -1. The crack initiation locations and the crack growth paths as well as the fatigue lives are identified. The simulation results are compared to the results of the previous experiments, showing an acceptable agreement
