渗流应力 meaning in English

seepage stress

In order to study the influence of evolvement of permeation character induced by mesoscopic structural characteristics on macroscopic mechanical behavior and fracture mechanism , a nonlinear constitutive equations describing the relationship between damage of rock and seepage is proposed based on mesoscopic damage mechanics and biot seepage mechanics theory and coupling system of flow & solid in rock failure process analysis , f - rfpa2d , is developed to simulate the variation of permeability as well as coupling mechanism between seepage and stress during the initiation , propagation and coalescence of cracks in rock . this study also extends the research field of original rfpa2d
为了分析细观结构特性变化引起渗透性演化对宏观力学行为的影响,并进行渗流应力耦合作用下岩石破裂机制的研究,本文基于细观损伤力学和biot经典渗流力学,建立了岩体损伤非线性本构方程和渗透率关系模型,开发出岩石破裂过程渗流-应力耦合分析系统( couplingsystemofflow & solidinrockfailureprocessanalysis简称f - rfpa2d ) ,拓宽了原有程序rfpa2d的研究领域。
