Effect of Non-Linear Constitutive Law on Column Buckling
Abstract eng: Columns with linear constitutive laws in bending can sustain higher than critical buckling load after buckling. In other words, they have stable post-buckling behavior. However, a class of materials such as redwood exhibits cubic nonlinearity in the constitutive law with softening effect. An analysis with simple idealized model reveals that such cubic nonlinearity in the constitutive law diminishes the domain of post-buckling stability, and lead to catastrophic collapse. This work further investigates the finding by taking into account the nonlinear constitutive law into beam theory.
