An Energy-Based Approach for Fatigue Crack Growth

Abstract:

Article Preview

A fatigue crack growth model under constant amplitude loading based on the total plastic energy dissipation per cycle ahead of the crack was proposed. With the energy balance concept, the crack growth rate was correlated with the total plastic dissipation per cycle, and the total plastic dissipation per cycle was obtained through 2-D elastic–plastic finite element analysis of a stationary crack under constant amplitude. The predictions of the model were in good with the experimental results.
