This benchmark model shows how to perform a high-cycle fatigue analysis for non-proportional loading using critical plane methods.
A benchmark model for the fatigue module. A cylindrical test is subjected to normal and shear load scenario. Three stress based models: Findley, Matake, Normal stress, are compared to analytical values and to each other. The non-smooth...
A load carrying component of a structure is subjected to multi-axial cyclic loading during which localized yielding of the material occurs. In this model you perform a low cycle fatigue analysis of the part based on the...
A benchmark model of the Rainflow counting algorithm compares results between ASTM and COMSOL fatigue module using a flat tensile test specimen. An extension is made for the cumulative damage calculation following the Palmgren-Miner model...
A frame with a central cutout is subjected to a random load consisting of 1000 load events. The external load, recorded using three strain gauges, is simulated using superposition of three unit loads. The stress state around the cutout is...
This example shows two structural analyses of a car wheel rim. The parametric solver is used to simulate a varying load along the boundary of the rim. The model solves for both the anti-symmetric and symmetric load cases. The two...
