to investigate the characteristics of stress-strain relation and the dissipation of pore water pressure by the hollow cylinder apparatus. It is found that the stress-strain response and the dissipation... strength recovery stage is longer. A stress-strain model and a dissipation model of excess pore water pressure of liquefied sand-gravel composites are established, in which the initial confining......
of the magnitudes of the two step-loadings are given and the complete solutions for the dynamic response are constructed, whose plastic dissipation is also discussed. Different from the previous... that the plastic dissipation will be 1/3 of the input energy when plastic deformation occurs. Key words: step-loading; dynamic plastic response; deformation mechanism; plastic dissipation

of calculating the energy in the process of breaking was presented, and the relationship between the strain and elastic energy and dissipation energy was also analyzed. The results show that the number... uniaxial/triaxial compressive condition, the variation tendency of the elastic energy, the dissipation energy and the total inputting energy is similar, and the elastic energy has a maximum value......

At the first stage of the testing, the strain curve and energy dissipation curve of the samples for a single cycle tend to drop sharply and then go into a slower... dissipation 上保护层开采能够使下部具有瓦斯突出危险性的煤层受到采动影响而减小突出危险性,是防治煤与瓦斯突出的有效措施.上保护层开采过程中巷道掘进,工作面开采,老顶初次来压,周期来压等对底板及被保护煤层产生反复的应力扰动,此时,被保护煤层与上保护层底板共同组成一种极复杂的岩石结构,由于其内部结构复杂,在不同的外部应力作用下会产生不同的宏观力学表现[1].岩石在不同应力条件下的破坏实际上是内部......
contribution, energy dissipation, as well as volumetric response. Numerical results show that both the magnitude and the directional variation of normal contact forces govern the development of macroscopic strength and the reinforcing effects of joint protrusion height can be attributed to the accelerated energy dissipation across the particle assembly and the intensive mobilization of the geogrid......
