Abstract: As the limit strains are path dependent and it is impossible to define them experimentally for all possible strain path combinations, in this work, a method is proposed to obtain them numerically. Simulations are carried out using an explicit finite element package LSDYNA and the proposed method is validated with analytical solution proposed by Soren and Rice. Limit strains for deep drawing operation are found out with varying die corner radius and blank holding force.
