Research on initial solution estimation in inverse approach for sheet metal forming

Initial solution estimation plays a crucial role in inverse approach for sheet metal forming, it influences the speed in the convergence procedure. Based on the research of some recent algorithms work of the initial solution estimation of inverse simulation approach, an improved algorithm, named projecting and averaging linear deformation method, is presented, which enables the inverse approach more stable and improves its convergence greatly. In order to verify the proposed method, some examples were investigated.
