| 1. | That is the identification of material parameter is done through the true deformation increment in the loading stage before , loading increment , and the stress state by artificial neural networks , after this , we can get loading increment for the next deformation stage by the artificial neural networks trained by stress stage , target deformation increment and the identified m value 即首先根据上一步加载材料的实际应变增量、所加应力增量以及材料所在的应力状态识别出材料物性参数m值,然后再根据材料加载后的应力状态、目标应变增量以及识别所得m值,由训练好的识别应力增量的人工神经网络产生应加的载荷增量。 |
