A unified damage approach for predicting forming limit diagrams

Article Abstract:

A new unified method for predicting the forming limit diagram (FLD) of aluminum alloy 6111-T4 was constructed based on the damage mechanics theory. This approach was compared with other conventional damage methods for predicting FLD. Results have shown that the new approach predicts lower FLDs than most other methods. Moreover, using new damage instability criteria, the localized necking curve and diffuse necking curve intersect at the same point when the minor strain is equal to zero.

Plastic deformation of a perforated sheet with non-uniform circular holes along the thickness direction

Article Abstract:

A yield criterion is discussed for the perforated sheet with uniform circular holes by employing an equivalent continuum approach, which is then applied to examine the plastic deformation of the perforated sheet with non-uniform circular holes. The analytical results predicted by the theory are verified by the results obtained from the finite element analysis and from experiments.

Forming limit analysis of sheet metals based on a generalized deformation theory

Article Abstract:

The development of a generalized method to predict forming limits of sheet metals is presented. A generalized deformation theory is proposed and the vertex theory is employed in the analysis to characterize the localized necking mechanism in elastoplastic materials.
