dc.description.abstract | In order to obtain reliable solutions for the initiation of localized instability in sheet metal forming, numerical procedures are developed for predicting forming limits using crystal plasticity. The Marciniak-Kuczynski (M-K) method is employed to calculate the initiation of the instability with rate-dependent elastic-crystal plasticity for cubic metals. The Nelder-Mead (N-M) direct search and Newton-Raphson (N-R) methods are used to solve the highly nonlinear equilibrium and associated compatibility equations under the M-K scheme. The N-M method eliminates the need of the first-order derivatives of the constitutive equations that may not be readily available for complex material models. The numerical results show that the calculation time using the N-M method is comparable to that using the N-R for the highly nonlinear M-K equations if the simplex size parameters are properly optimized.
