应变速率效应 meaning in Chinese
effect of rate of strain
Examples
- The effect of strain rate on mechanical properties of steel in hydrogen
在氢环境中钢的应变速率效应 - The research indicate that the structured soft clay has below several characteristic , the viscous strain is produced during the stage of primary consolidation and of second consolidation , and in the prophase , the relation of stress - strain - strain rate is unique , so the form of constitutive model , such as , f ( v ' , e ) = 0 , f ( ' v , e , t ) = 0 , ca n ' t describe strain behavior of soil skeleton rationally ; the time - dependent properties involve three aspects , in addition the time - dependent strain , apparent preconsolidation pressures that depend on strain rate , and the effect of creep compression on apparent preconsolidation pressures ; because of holding structural strength , the mechanics characteristic is determined by the magnitude of stress , and the compression curve is composed of several sections . by combining structural yield stress and it ' s characteristics with the improved time line model , a new one - dimensional elastic visco - plastic consolidation model is established
研究结果表明，结构性土的固结过程具有以下特性：主固结和次固结阶段都包含有因土骨架的粘滞性移动而产生的变形，而且在正常固结阶段，存在应力?应变?应变速率的唯一性， f ( _ v ， e ) = 0 、 f ( _ v ， e ， t ) = 0形式的本构关系不足以描述土骨架的变形行为；固结压缩过程中的时间效应包括三个方面的内容，除了应力应变关系与时间相关外，还包括粘滞性变形引起表观前期固结压力增加和屈服应力的应变速率效应；软土的结构性使其力学特性与应力水平相关，压缩曲线具有分段性。
