Research on FLD of H340LAD Niobium Alloy Steel Based on the Finite Element Method
Liwen Tian, Changfeng Men
Abstract: The Forming Limit Diagram can simply and intuitively reflect the form ability of the sheet. In this paper based on the finite element simulation software Dynaform, combined with maximum load judgment criterion and the strain path judgment criterion, obtained ultimate strain data and accurately obtained H340LAD niobium hsla steel forming limit diagram. Using finite element simulation method is more convenient to study the material parameters (yield function index m, thick anisotropic index r, hardening index n) on the influence law of forming limit curve, provided the basis for study of FLD.
Keywords: Finite element simulation, FLD, H340LAD niobium hsla steel, material parameters, forming limit curve
