Strength enhancement of austenitic steel sections due to cold-forming

Popis výsledku v původním jazyce

Austenitic grade is the most common type of stainless steel which can be hardened significantly by cold working. The manufacturing process of the cold-formed thin walled sections leads to a notable change in the mechanical properties. These changes of the properties are characterized by the co-existent residual stresses and equivalent plastic strains due to cold forming and has a significant effect on their structural behaviour and strength. This paper determines the effect of cold-forming on the properties by developing an analytical model using software Maple. The increased material strength is determined at different stages of cold forming (coiling, uncoiling including flattening and cold bending) considering the residual stresses and plastic strain. The analytical model is validated with the previous test results. A parametric study is presented to investigate the effect of increase of yield strength with the change of the bending radius and the result is compared with the previously published predictive models of strength increase.
