1) strain ratio
应变比
1.
Cyclic load-deformation curves of materials under tension-compression cycle and torsion cycle for different strain ratio were determined experimentally by using incremental step loading and total strain controlling technique in room temperature.
在不同应变比下,按照总应变控制等幅循环阶梯加载方式,测定了材料在拉-压、拉-拉及扭转循环下相应的循环载荷-变形曲线,得出了材料的循环应力及应力比随应变比的变化关系。
2) Proportion of strain value
应变比例
3) Principal strain ratio
主应变比
1.
Analyses of observed ground strain dstum by the abnormal theory of Principal strain ratio from 1990.
本文利用主应变比异常理论分析了祁连建站以来地应变观测资料,认为肃南──祁连断裂段上及附近发生的地震是由于构造应力场的变化,在引张应力状态下,正断层或走滑断层易于活动而导致的。
4) specific strain energy
比应变能
5) cyclic strain ratio
动应变比
1.
By the non-dimensional analyses of post-cyclic loading strength, pore pressure and cyclic strain, the relationships between the post-cyclic loading strength ratio and the cyclic strain ratio or the pore pressure ratio are established.
通过对土样的不排水强度、孔压和动应变的无量纲化处理,确定了周期荷载作用后粉质黏土的不排水强度比与动载引起的孔压比和动应变比之间的相关关系。
6) unit strain energy
应变比能
1.
Based on the description of Mohr-Coulomb(M-C) and Drucker-Prager(D-P) yield criteria with invariant of stress,a formula for error estimation of unit strain energy between the two stress states is established in the deviatoric plane of the principal stress space,which satisfies M-C and D-P yield criteria respectively.
基于应变比能的概念,在偏平面内建立了分别进入Mohr-Coulomb(M-C)和Drucker-Prager(D-P)屈服面时所需形状改变比能的差值公式,获得M-C材料参数向D-P计算参数等效的统一性方案。
