改进的RBF作近似模型进行预测,更好的全局和局部精度(ExRBF as a RSM for prediction)

Optimization technique RSM with Grey relational analysis

In this paper, an anisotropic formulation of the Gurson-Tvergaard-Needleman (GTN) damage model is used for simulating the deep-drawing of a rectangular box made from an AA6016-T4 metallic sheet. The model is implemented as a VUMAT routine in the ABAQ
