项目摘要
For accurate numerical simulation of sheet metal forming, the use of appropriate material models that describe the workhardening, the Bauschinger effect and the anisotropy of sheet metals is of vital importance.In the present work, material properties at a large strain were determined by the elasto-plasticity inverse approach. For the large strain workhardening characteristic, the weighting parameter in the combined Swift-Voce model was identified from an in-plane cyclic bending experiment. For the determination of the Bauschinger effect, a set of material parameters of the Yoshida-Uemori kinematic hardening model were identified from a three-point cyclic bending experiment. For the anisotropy, the sixth-order polynomial type yield function was proposed, and based on the model, the description of the evolution of anisotropy with increasing plastic strain was presented.
为了对金属板材成形进行精确的数值模拟,使用适当的材料模型来描述金属板材的加工硬化、包辛格效应和各向异性至关重要。在目前的工作中,大应变下的材料性能是通过弹塑性逆方法确定的。针对大应变加工硬化特性,通过面内循环弯曲实验确定了组合 Swift-Voce 模型中的权重参数。为了确定鲍辛格效应,从三点循环弯曲实验中确定了吉田-上森运动硬化模型的一组材料参数。 对于各向异性,提出了六阶多项式屈服函数,并基于该模型描述了各向异性随塑性应变增加的演化过程。
