Under triaxial compressive conditions, with an increase of loading, the propagation and sliding of microcracks in rocklike materials become increasingly intense and lead to a serial of consequences, such as nonlinear stress-strain relationships, deterioration of elastic modulus, anisotropic deformation, volumetric dilatancy and irreversible plastic strain, etc..

三维压缩条件下，随着载荷的逐渐增加，岩石类材料内部微裂纹的传播与错动不断加剧，最终导致非线性应力－应变关系、弹性模量的减小、变形的各向异性、体积膨胀以及不可逆塑性变形等结果。

随着加载压力的逐渐升高，灵芝孢子在超临界二氧化碳的静水压力作用下内部压应力逐渐增加，产生弹性变形而体积缩小，并在孢子中储存很高的弹性应变能。

The apparent degree of network chains for the different swollen extent of the same unswollen hydrogel sample increased linearly with the increase of swelling ratio, however, the apparent modulus did not decrease monotonously with the increase of swelling ratio. Furthermore, the dependence of apparent degree of network chains on swelling ratio had nothing to do with the swelling agent. The above results reflected the changes of entanglement and the contribution of entanglement under different swelling ratio, and the results could be explained with the theory of Flory-Erman's constrained junction model and LangleyGraessley relation.

发现同一水凝胶样品的不同溶胀程度试样经应力应变测试得出的表观网链密度随体积溶胀率的增加而线性增加，等效模量并不随溶胀程度的增加而单调减小，而表观网链密度的溶胀程度依赖性与所选用的溶胀剂无关，该结果反映了不同溶胀程度下缠结的变化及缠结对弹性的不同贡献，并可由Flory-Erman的constrained junction模型及Langley-Graessley公式得到解释。
