accumulative plastic strain的用法和样例：
- The discussion is focused on the relation of ratcheting to the plastic modulus and accumulated plastic strain.
- LCF life could be well expressed by plastic strain energy.
- accumulated plastic strain
- The final configuration is identical to that in (a), and the total plastic strain is six atomic spacings.
- It can he used to compute many appropriate scalar quantities such as temperature, displacement, effective stress and effective plastic strain.
