Fatigue Life Prediction in FEA – A Comprehensive Guide (ANSYS, Abaqus, fe-safe & More)
Introduction Fatigue failure is one of the most common causes of unexpected breakdowns in engineering structures subjected to cyclic loading. Even when stresses are well below a material’s yield or ultimate strength, repeated load cycles can initiate small cracks that grow over time, eventually leading to catastrophic fracture. Predicting fatigue life (the number of cycles […]
Creep Strain vs Stress Relaxation, A practical guide for CAE users
Description Learn what creep is, how temperature and stress control creep life, and which creep models CAE tools (ANSYS, COMSOL, Abaqus and others) use. Simple equations, practical CAE workflows, ASME / code context, and industrial project examples (boilers, pressure vessels, turbines, heat exchangers). What is creep? Creep is permanent deformation that accumulates over time when […]
Fatigue Life Estimation: Goodman vs. Gerber Correction Methods
Fatigue life estimation is critical in engineering applications where components endure alternating stresses over time. This tutorial explores how Goodman and Gerber correction methods are used to estimate fatigue life for a rotating shaft, providing a clear understanding of their effectiveness in handling different mean stress scenarios. https://engineeringdownloads.com/wp-content/uploads/2025/06/goodman-gerber.webm Stress Analysis (FEM) […]
