3)Coulomb-Mohr criterion库仑摩尔准则
1.Growth degree, azimuth and dip angle of the tension fissures and shear fractures were estimated using Griffith criterion andCoulomb-Mohr criterion.在三维构造精细解释和综合利用构造演化、露头、岩心、测井资料描述裂缝信息的基础上,利用有限元数值模拟方法预测潜山油藏古构造应力场分布,采用格里菲斯准则和库仑摩尔准则判断张裂缝和剪裂缝的发育程度、裂缝方位及倾角。

1.Generalized yield condition of bended circular plate respect toMohr-Coulomb criterion;圆板中摩尔库仑准则的内力屈服条件
5)Mohr-Coulomb model摩尔-库仑模型
1.The settlement and horizontal displacement of the subsoil are analyzed by FEM program applying modified Cam-clay model to subsoil andMohr-Coulomb model to fill.对宽路堤填土的高度、刚度以及地基土刚度的3种不同组合,将路堤和地基一同划分网格,地基部分采用修正剑桥Biot固结耦合模型,填土部分采用弹塑性摩尔-库仑模型,进行地基沉降和水平位移有限元分析,得出宽路堤地基沉降和水平位移的分布与路堤填土高度、刚度以及地基土刚度等因素密切相关:在地基土较软、填土刚度不大的情况下,最大沉降量发生在路堤坡肩下,且随堆载的继续,最大沉降位置向内移动,且与路堤中心处的沉降差减小;当地基土较硬时,水平位移量变小,在路堤两侧不再出现最大沉降量,路堤下地基沉降差减小;当填土刚度增大,地面沉降量、水平位移量和沉降差都减小,随堆载的继续,沉降差减小显著。

1.Aimed at the incorrect cognition of stratum shapes near wellbore after the high-pressure gravel packing and the neglect of the compaction of bottom-hole stratum in the frac-packing mathematical model available,the relations were given based on theMohr-Coulomb criterion and the basic theory of plain-strain axisymmetric problem.针对高压砾石充填后近井地带形态认识不清以及现有压裂充填数学模型中没有考虑井底岩层压实的情况,根据摩尔-库仑准则和平面应变轴对称问题的基本理论,推导得出了疏松砂岩高压挤压时近井地带的应力、应变和位移等参数与压实区半径的关系,并通过算例分析了疏松砂岩岩体的内摩擦角、杨氏模量等参数对高压挤压结果的影响。
2.Several problems about SRFEM are discussed such as the definition of safety factor, utility condition ofMohr-Coulomb criterion and access to calculation parameters after the adequate praise and affirmation of i.在充分肯定其优势及特点的同时,从安全系数定义、摩尔-库仑准则的应用条件、计算参数选取等方面,探讨了有限元强度折减法的若干问题。

多次库仑散射多次接续发生的库仑散射为多次库仑散射。多次库仑散射后带电粒子的净偏转角近似地正比于该粒子的电荷，反比于其动量p与速度v的乘积pv。在核乳胶及重液泡室中，常用此性质测定带电粒子的pv值。
