abaqus-fatigue-analysis

To predict fatigue life from Abaqus FEA stress results, extract stress histories from ODB files and apply fatigue criteria like S-N curves or strain-life methods. This Skill automates calculating cycles to failure and assessing durability under cyclic loading.

High-cycle fatigue analysis uses S-N curves to calculate cycles to failure for elastic loading, while low-cycle fatigue uses strain-life methods for plastic deformation. This Skill guides users through applying both regimes based on their Abaqus FEA stress results.

Calculate cumulative fatigue damage from variable amplitude loading by applying Palmgren-Miner's rule. This Skill implements Miner's rule to assess cumulative damage from variable amplitude loading histories extracted from your Abaqus stress results.

Yes, you can use Abaqus stress results for fatigue analysis while considering mean stress factors. This Skill guides users through extracting stress histories and applying fatigue criteria that account for mean stress and stress concentrations.
