摘要
复合材料和橡胶粘结成一体的防振橡胶在机械载荷的作用下,经常发生因粘接界面破坏而导致的结构失效。用 型加载下的双悬臂夹层梁试样,借助有限元对橡胶夹层/复合材料粘接界面的破坏进行研究,指出了橡胶夹层厚度变化以及界面裂纹长度发生改变时,橡胶/复合材料粘接界面裂纹前沿的应力和载荷作用方向上的应变的变化,及其临界断裂条件。
The jar-proof rubber, a combination of composite material with rubber, often induces the damage of the structure due to the fracture of the adhesive interface when it works under the mechanical load. In virtue of the finite element, using double cantilever sandwich in mode I as specimen, the fail mechanism of the rubber interlayer on the adhesive interface is studied. The changes of the stress and the strain in the loading direction as the rubber thickness or the crack length on the interface is changed are described.
