Theoretically, a member can only behave linearly while the maximum stress does not exceed the yield stress, and so the presence of residual stresses or stress concentrations will cause early […]

Inelastic analyses can be generalized into two approaches. The first approach is known as plastic hinge analysis. The analysis assumes that structural elements remain elastic except at critical regions where […]

Material nonlinearity may be due to nonlinear elasticity, plasticity or viscoelasticity of the material.
