Finite Element Analysis of Punching Press Operation: Meshing Effect

Effect of the meshing methods on nodes and elements numbers during meshing of punching press operation has studied. FEA is a great way of studying the stresses, strains and deflection generated before going to real practices. Meshing serves significant role towards the correct solution from FEA. Effect of the meshing methods like patch independent, patch conforming and sweep have studied in the present paper. Modelling of the punching assembly which includes punch, sheet, blank holder and die has accompanied first then the meshing methods have applied to study the nodes and elements number. Three element sizes 10mm, 5mm and 1mm have been considered. Analysis of meshing methods dictates that the decrement in element size increases the nodes and elements number which provides fine meshing. Results also shows that sweep meshing method can be better with low element size. Patch independent method has found to give more number of nodes and element or fine meshing.
