The focus of this study is on the characterization local plastic deformation and failure functionally graded 22MnB5 plates after hot stamping using an in situ approach. Various forming strategies at elevated temperatures are performed differentially tempered tools to locally tailor microstructure. By controlling cooling rate, as well martensitic ferritic–pearlitic microstructures obtained. Expe...

In this paper, we have modified the stress integration scheme proposed by Choi and Yoon [1]; which is based on numerical approximation of yield function gradients, to implement in finite element code ABAQUS three elastic isotropic, plastic anisotropic constitutive models with yielding described Yld2004-18p [2], CPB06ex2 [3] Yld2011-27p [4] criteria, respectively. We developed both VUMAT UMAT su...

forming limit curves are used as a parameter in finite element analysis to control the material's level of formability. in this research, forming limit diagram (fld) of ss304l sheet was obtained by abaqusfinite element software. in practice, the experimental determination of a forming limit curve is a very time-consuming procedure which requires special and expensive equipment. forming limit di...
