| 摘 要： | 建立了与材料延伸率相关的轮盘弹塑性破裂准则。为了验证所提出破裂准则的正确性，采用非线性有限元对变厚度轮盘破裂试验件的破裂转速进行了预测，并与试验结果进行了对比。结果表明，二者吻合很好。

| Abstract: | The elastic-plastic disc burst criteria related to material elongation was established.In order to validate the criteria,the burst rotational speed of the variable thickness test disc were predicted using the nonlinear finite element method.The prediction were compred with the test data.The results show the prediction were in accord with the test data. |
