不可逆变形 meaning in English
irreversible deformation
irreversible transformation
nonreversible deformation
Examples
- Based on a large numbers of model / simulation test of the intermittent cracked rock - like samples , fatigue strength , fatigue deformation and crack appear in preexisting cracks tips , the growth of crack , the pattern of crack coalescence are studied / analysed systemically by means of cyclic load and static load , in the course of the model test , the difference between cyclic load and static load of crack appear in preexisting cracks tips , the growth of crack and the pattern of crack coalescence are observed and analysed
在试验过程中，观察并分析了循环加载方式下，预置裂隙端部裂纹萌生、扩展、岩桥贯通模式与静载方式下的差异；探讨了疲劳裂纹萌生、扩展的机理，分析了加载频率、荷载水平对裂隙试样疲劳强度、疲劳变形(总变形和不可逆变形)的影响规律。 - Supposed the two nonreversible deformations both obey the drucker law , the plastic loading function was established based on experimental data and the plastic work was used as hardening parameter supposed loess damage is mostly due to shear and the damage potential function has the same form of the equivalent plastic strain line in the plastic part , the damage potential function was gained by fitting the test data
假定两类不可逆变形都服从drucker公设，根据试验数据确定以塑性功为硬化参数的塑性加载函数。认为损伤主要由于剪切产生，假定损伤势函数与塑性部分的塑性剪应变等值线具有相同的形式，通过试验数据拟合得到损伤势函数，然后根据损伤理论推导建立q1黄土的弹塑性损伤本构模型。
