Abstract

The present paper aims at obtaining insights on the strength behaviors of ship hull plates under uniaxial cyclic loads. The residual ultimate strength of ship hull plates under uniaxial cyclic load is studied by numerical analysis using nonlinear finite element method. A series of tests are also conducted for comparison and verify the reasonability of numerical results. The accumulated plastic damage and crack propagation from the low cycle fatigue damage during cyclic load are both considered in present study. From the numerical results and tests some significant conclusions are drawn to the residual ultimate strength of plates under uniaxial cyclic loads.
