The envelopes of softening curves for post yielding of rock mass materials are also presented to give the complete computational model.
同时，提出了岩体材料屈服后的包络型软化曲线，为岩体材料的非线性计算提出了完整的计算模型。

The stress - strain relationship of soil estabished from shear tests is distinguished into two kinds-progressive hardening type and post-peak softening type.
The increases of enzymatic activity of cell wall-degrading enzymes were regulated by genes. Thus the research on post-harvest biotechnology provided new ways to study the fruit ripening and softening.
