【摘要】 对结构钢胶接接头在拉剪载荷作用下的破坏过程进行了分析讨论。测定了被粘物破坏面的显微硬度并考察了胶层厚度、搭接长度变化时的情形。结果表明：现有拉剪载荷作用的力学模型不能说明接头的实际破坏过程更多还原

【Abstract】 The destruction procedure of steel joints under the tensile shear loading is discussed in this paper.The microhardness of the surface layer of the adhesive is measured and the effects of thickness of adhesive and lap lengths are alsoanalyzed.The current mechanical models for describing the effect of the tensile shear load can not be used to explain the actual destruction procedure.更多还原
