Although there are many experiments under multiaxialstress states, most of the results mainly concern to the strength and failure criterion of concrete.
Based on experimental data and finite element analysis results, a low-cycle fatigue life model is proposed for the powder metallurgy superalloys under multiaxialstress states.
