摘要: The sheet metal forming is a manufacturing process widely used industrially. quality and efficiency of the dependent on correct choice parameters understanding behavior. identification regions where stretching and/or deep drawing occurred during can aid through tools design optimization. This work consisted evaluating three punch models with varied geometries. purpose this was to simulate different geometries using ANSYS/LS_DYNA program compare results those reported in literature. An evaluation also made chosen program's response (validation). material model Barlat's model. friction coefficient influence investigated. A comparison major true strain (e1) obtained by simulation compared experimental indicated that able satisfactorily reproduce found practice for DC 06 steel.
