The models in common use with elastoplastic analysis of rock mass, conception of critical state and the cap models that reflect strain hardening (or softening) of rocks are discussed.

介绍了岩体弹塑性分析常用的模型、临界状态的概念以及反映岩石塑性应变硬化(及软化)的帽式模型。

The rock strain softening after rock peak and the shear expansion properties affect the plastic critical state.

岩石峰后的应变软化特性和剪切膨胀特性对塑性临界状态有重要影响。

The lower limit of temperature at which this occurs is known as the softening point or critical temperature.

呈现这一性质的温度下限称为软化点或临界温度。

In the meantime, given the signs of weakness in the world economy, not just in Europe but also some softening in Asia, it's critical that we take the actions we can to strengthen the American economy right now.
