Tensile experiment showed the existence of equidistant zones of strain localization and deformation activation of one of zones at the stage of macrofracture initiation. For uniaxial compression tests of granite, it has been found...

... ABSTRACT: This paper presents an innovative bolt which has the Negative Poisson's Ratio effect (NPR bolt). The NPR bolt can absorb energy and sustain high constant resistance and large deformation. The working principle of this new type of bolt is introduced and a series of dynamic laboratory...

... ABSTRACT: Impact cratering is a fundamental geological process in the solar system. The formation of impact craters is a highly dynamic and complex process that subjects the impacted target rocks to numerous types of deformation. The impact process can be subdivided into three subsequent...
