The paper describes some recent developments in finite element methods for analysis of bulk forming and sheet stamping processes. The developments include new stabilized linear tetrahedra for non linear solution of problems in solid and fluid mechanics and an enhanced version of the three node rotation-free BST shell triangle for analysis of thin shells. Applications of the new elements to casting and sheet metal forming problems are shown
