| 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.
