Failure criterion for soft rocks considering intermediate principal stress
International Journal of Mining Science and Technology, 2021 The significant differences between hard rocks (more brittle) and soft rocks (more ductile) may suggest the use of different failure criteria. A strength criterion for soft rocks that includes intermediate principal stress was proposed. The new criterion

Experimental methodology of study of damage initiation and development in textile composites in uniaxial tensile test [PDF]
, 2008 Damage in textile composites is closely connected with the internal micro- and meso-geometry of the reinforcement, and reveals features, which are not present in the damage processes in classical laminates. This paper proposes a test sequence intended to

Evaluation of local damping effect on static and dynamic behaviors of granular materials using DEM modeling [PDF]
مهندسی عمران شریف, 2022 Frictional sliding may not be sufficient for the stability of a system. In almost all models in the Discrete Element Method (DEM), a local non-viscous damping is used to balance the system by applying a damping force with a magnitude proportional to the ...
