Simulation fatigue 1000 cycles Abaqus

Description

Simulation fatigue 1000 cycles Abaqus

In this tutorial , we simulate 2D fatigue in Abaqus software by using Paris law

A plate with a circular hole is studied. The specimen has a length of 0.34 m, a thickness of 0.02 m, a width of 0.2 m, and a hole radius of 0.02 m

In the low-cycle fatigue analysis, two steps are involved. A static step is used to nucleate a crack at the site of stress concentration prior to the low-cycle fatigue direct cyclic step, in which a cyclic distributed loading with a peak value of 350 KPa is specified

Equal and opposite loading are applied at both ends in the longitudinal direction

In this example , we use Direct cyclic analysis and analyze 1000 cycles

crack propagation in 164 cycle

crack propagation in 547 cycle

crack propagation in 841 cycle

crack propagation in 1000 cycle
