Based on the experimental results and previous studies, the stress ratio at the failure (Mf) under different confining pressures is modified, and the pressure dependency of plastic modulus is discussed. Considering the i...

Based on the concept of true stress and the strain equivalence hypothesis, a three-dimension elastic-plastic damage constitutive model for rock is established. Combining the nonlinear unified strength model as the yield ...

During aging, the brain undergoes changes that impair cognitive capacity and circuit plasticity, including a marked decrease in production of adult-born hippocampal neurons. It is unclear whether development and integrat...

The discontinuities distributed in underground structures are the important factors that affect the mechanical characteristics of rock mass, and to study the mechanical behavior of rock discontinuities under cyclic loadi...

There are problems when dealing with the dredger fills using the traditional vacuum preloading method, for example, the treated area can not be too large and the plastic-sheet maybe leaks. To solve these problems, the ne...
