| 中文摘要: |
| 采用有限元分析软件ANSYS Workbench建立橡胶材料开臂缝设计的十字形试样的数学模型，并模拟分析臂缝及其参数对中心测试区域应力分布均匀性的影响。结果表明：开臂缝可以提高十字形试样中心测试区域应力分布的均匀性；臂缝宽度和长度对试样中心测试区域的应力分布无明显影响，但臂缝宽度增大对拉伸臂的应力分布影响较大，臂
缝宽度为1 mm、长度为20 mm较好。本研究可为橡胶材料双向拉伸试验标准试样的制备提供参考。 |
| 英文摘要: |
| The mathematical model of the cruciform specimen with open arm gap design by finite element analysis software ANSYS Workbench was established，and the influence of arm gap and its parameters on the stress distribution uniformity in the central test area was simulated and analyzed. The results showed that the opening of the arm gap could improve the uniformity of the stress distribution in the central test area of the cruciform specimen. The width and length of the arm gap had no significant influence on the stress distribution in the central test area of the specimen. However，the increase of the width of the arm gap had a relatively greater influence on the stress distribution of the extension arms. It was found that the suitable width and length of the arm gap were 1 and 20 mm，respectively. This study provided a reference for the preparation of standard sample for the biaxial tensile test of rubber material. |
