In the current research an advanced criterion with non-associated flow rule (non-AFR) for depicting the behavior of anisotropic sheet metals is presented to consider the strength differential effects (SDEs) for these ...

One of the new research fields in plasticity is related to choosing a proper non-associated flow rule (NAFR), instead of the associated one (AFR), to predict the experimental results more accurately. The idea of the current ...

In the current research with novel first and second differentiations of a yield function,

Euler forward along with Euler backward with its consistent elastic-plastic modulus are

newly implemented in finite ...

In this paper to predict the critical conditions for onset of elastic-plastic wrinkling of flange of a two-layered circular blank during the deep-drawing process a closed-form semianalytical elastic-plastic solution using ...

In the current research to model anisotropic asymmetric sheet metals a new non-AFR criterion is presented. In the new model, Modified Yld2000-2d proposed by Lou et al. (2013) is considered as yield function and Yld2000-2d ...

Based on two-dimensional plane stress wrinkling model of an elastic annular plate and a bifurcation functional from Hill s general theory of uniqueness for polar coordinate, the critical conditions for the elastic wrinkling ...
