根据高孔率材料的结构特点提出模型 ,推导出该材料抗拉强度与孔率的数学关系式 ,通过高孔率泡沫镍为例的实验 ,证明该理论式较好地反映了高孔率金属抗拉强度随孔率的变化规律 .
According to the structural characteristics of high porosity materials, the model was proposed and the mathematical relationship between the tensile strength and porosity of the material was deduced. The experiments on high porosity nickel foam show that the theoretical formula better reflects the high porosity metal Tensile strength changes with the rate of porosity.
