DOI: 10.1007/s00603-017-1188-0
Abstract: Abstract The strength decay that occurs in the post-peak stage, under low confinement stress, represents a key factor of the stress–strain behaviour of rocks. However, for soft rocks this issue is generally underestimated or even… read more here.

DOI: 10.1007/s10706-017-0377-7
Abstract: Scale effects refer to changes in mechanical behaviour associated with the volume of material being loaded or deformed. Scale effects in rocks and rockmasses are particularly complex, as an increased volume of interest changes not… read more here.

DOI: 10.1007/s10706-017-0414-6
Abstract: Engineering research has shown that the surrounding rock of deep roadways experienced many times of post-peak cyclic loading and unloading. So studying on rock mechanical characteristics of post-peak loading and unloading is helpful to control… read more here.

DOI: 10.1016/j.jseaes.2017.04.020
Abstract: Abstract A reconstruction of the pressure–temperature–time (P–T–t) path of high-pressure eclogite-facies rocks in subduction zones may reveal important information about the tectono-metamorphic processes that occur at great depths along the plate interface. The majority of… read more here.

DOI: 10.1016/j.tust.2017.09.013
Abstract: Abstract Stability analysis of rock tunnels is a complex problem because of various types of uncertainties present in the rock mass properties and hence probabilistic approaches are used to systematically consider these uncertainties in the… read more here.
