The 3-D model contains nodes connected by shell finite elements. 3-D model is modified by converting each quadrilateral shell finite element to triangular shell finite elements. Respective averaged nodal curvatures of all nodes of the 3-D model is calculated based on the 3-D geometry. A 2-D mesh model is created by unfolding the 3-D model to a plane while maintaining all corresponding triangular shell finite elements between the 2-D and the 3-D models as similar triangles. An estimated pre-stamped shape of a workpiece used for manufacturing the product/part is obtained by iteratively updating the 2-D model with a set of internal nodal forces with respect to the 3-D model and with a set of nodal force adjustments based on the respective averaged nodal curvatures."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Numerically estimating a pre-stamped shape of a workpiece used for manufacturing a product/part with deep draw metal stamping","description":"A 3-D mesh model represents 3-D geometry of a product/part manufactured with deep draw metal forming process.
