摘要: 本文研究了处于同一平面上的两组性能各异、交替出现的子节理面所组成的组合节理面的抗剪力学性质。通过对脆—脆、脆—塑、塑—塑三种类型的组合节理面的模型抗剪试验,得出了组合节理面的抗剪强度与各单体(又称子节理面)材料在组合节理面上所占的面积、单体交替出现的次数及抗剪方向等之间的关系。这些结论在实际工程应用方面有着非常重要的意义。
Abstract: Shearing mechanical behaviors of composite joints model with consist of two kinds of different characters of joints and various inter-appearances in one plane have been studied in this paper. After a series of experiments on brittle-brittle, brittle-plastic, plastic-plastic type composite joint models, follow conclusions have been gotten. The shearing strength of composite joints has a relation not only with the area of sub-joints, but also with the times of inter-appearances of two sub-joints(K); and the shearing strength of composite joints has a relation with the shearing direction, that is to say, the shearing deformation-failure of composite joints is gradual. These conclusions are very important and useful for practical engineering.
