对典型结构钢的双悬臂梁试件的中低速韧性撕裂的实验进行了准静态模拟。
A quasi static approach is presented for ductile tearing test of double cantilever beam specimen by using the model of elastic beam on elaso plastic foundation.
根据六种典型应力集中试件的应变电测试验，用电测数据建立灰色模型，预测应力集中问题的峰值应力。
The gray modeling method need less test data and is of high precision in prediction. Therefore, the gray model is feasible to a real time test of the strain or stress concentration problem.
