摘要

Method of design and manufacture of cold stamped metal components, comprising: - characterization tests of the material (410) of the component under conditions of supply; - marciniak embossing tests (432) to extract deformation measurements and elasto-plastic parameters of the material; - simulation of embossing tests (440), obtaining an objective structural model (464), - reverse drawing simulations (450), obtaining a source model (466) with estimation of deformations and thickness changes in the drawing; - mapping (462) of the deformation results of the source model (466) on the objective structural model (464); - assignment of estimated elasto-plastic parameters from response surfaces (470); - validation of the structural model (482) by simulation of the uniaxial tensile test (484); - manufacturing by means of a cold stamping process of the component using the validated structural model.
