Research on Load Bearing Behavior of Ship Stiffened Plates under Cyclic Loads

Article Preview

Abstract:

This paper adopts nonlinear finite element method to study the load bearing behavior of ship stiffened plates with different dimensions. The research focuses on the compressive ultimate strength, axial rigidity, and residual plastic deflection of the stiffened plates under cyclic compressive and tensile loads. The results indicate that the compressive ultimate strength and axial rigidity of stiffened plates decrease with the incremental cyclic loads significantly, meanwhile, the residual plastic deflection increases with the cyclic loads.
