摘要
提出了一种新的损伤定义及测量方法,确定了金属材料的损伤临界值,并进一步证明了金属材料的损伤就是金属材料的塑性变化。还导出了参量测量简便易行的静拉伸损伤计算式,给出了静拉伸损伤测量结果。
A new definition and measurement method of damage is put forward, the damage critical value of metal is determined and it is proved that damage of metal is exactly the plastic change of metal. A calculating formula of static tension damage is also deduced and the measurement of the parameters in this formula is easy to handle. The measurement results of static tension damage are given.
