摘要
根据Findley双曲正弦蠕变方程和Zhurkov方程,推导出材料诱发银纹时间和材料断裂时间的关系式。PVC在空气和10％H_2SO_4中的实验结果和这一关系式很好吻合。利用这一关系,即可由短期蠕变实验去预测承载塑料的长期使用寿命。
The relation between time to craze and time to fracture in plastics has been derived by Find-leys hyperbolic sine creep equation and Zhurkov's equation. The experimental results on PVC in air and 10%H2SO4 agree with the relation. Therefore, the long-term service life of load-bearing plastics can be predicted by short-term creep experiments.
