In recent years considerable research has been done in incremental forming due to its greater process flexibility and higher forming limits. In incremental forming the formability depends to a great extent on the toolpath via the incremental depth being used. A lack of fracture models to accurately predict failure in this process has hampered the utilization of incremental forming as an industrial level forming process. This paper deals with the use of a new fracture model in which both the effects of hydrostatic pressure and shear on damage are incorporated to accurately predict fracture in Single Point Incremental Forming.
