Abstract
The chapter describes the development of numerical models for analyzing stainless steel plates in compression. Material tests on coupons cut in the longitudinal, transverse, and diagonal directions are included, as are the results of tests on stainless steel plates. Detailed comparisons are made between the experimental and numerical ultimate loads and load-displacement curves. It is shown that excellent agreement with tests can be achieved by using the compressive stress-strain curve pertaining to the longitudinal direction of loading. The effect of anisotropy is investigated using elastic-perfectly-plastic material models, where the anisotropic material model is based on Hill's theory. The models indicate that the effect of anisotropy is small and that it may not be required to account for anisotropy in the modeling of stainless steel plates in compression. Furthermore, the displacements are generally underestimated; whereas, close agreement is obtained using the strain hardening models. In summary, stainless steel plates can be accurately modeled by using nonlinear strain hardening material models which are based on compression coupon tests for the longitudinal direction. The present study indicates that anisotropy may not be important for numerical analyses.
