additional effective stress的用法和样例：
- Effective stress management involves identifying and managing both acute and chronic stress.
- This also has the additional effect of removing soft goals, thus returning PES 2010 to its simulation roots.
- It can he used to compute many appropriate scalar quantities such as temperature, displacement, effective stress and effective plastic strain.
- Researches were carried out on internal blast loading and effective stress history at typical positions in the flat end plat and cylindrical shell.
- A liquefaction model for saturated sand soil is establishedaccording to the principle of effective stress under explosive loading.
