DUCTILITY OF HIGH PERFORMANCE STEEL RECTANGULAR PLATES UNDER UNIAXIAL COMPRESSION

摘要: Publisher Summary In order to possess the ductility of thin-walled steel structures, high performance steels whose material properties can be controlled may practically used in lieu ordinary steels. this chapter, elasto-plastic finite displacement analyses are carried out for uniaxial compressed rectangular plate with initial imperfections deflection and residual stress. The inelastic behavior on ultimate state thereafter these plates various aspect ratios width-thickness parametrically examined yield plateau length strain-hardening gradient. influences both parameters discussed from many analytical results. It follows that their two opportunely possessing plates. Additionally, required values (the gradient) cleared by illustrations efficiently study, under compression is elastoplastic analyses. found effectively controlling properties, length, strain hardening
