Finite element simulation and model optimization of blankholder gap and shell element type in the stamping of a washing-trough

A theoretical, numerical, and experimental investigation of plastic wrinkling of circular two-layer sheet metal in the deep drawing

“…The blank model contained 2106 elements. Coulomb friction coefficients of 0.1 and 0.12 were considered for aluminum and steel contact surfaces with oily lubrication, respectively (Chen et al, 2007). The materials were used in the power hardening law for each layer.…”

Studies on wrinkling and control method in rubber forming using aluminium sheet shrink flanging process

“…In the forming process, the elements of the blank on the top of the die were fixed. The coulomb friction coefficient of 0.1 was set for every contact surface [20]. The forming pressure is 200 bar.…”

Modeling of Extrusion Process and Application of Taguchi Method and Anova Analysis for Optimization the Parameters

“…Much research based on the finite element analysis has been done to analyze the metal forming processes. The accuracy and efficiency of FEA determine whether the simulation results are successful and reliable or not [11]. One question being frequently asked is whether a model is valid or invalid.…”
