DOI: 10.1007/s11440-021-01145-5
Abstract: Fracture mechanics analysis of shear band propagation requires knowledge of the material’s shear fracture energy and its related properties such as the characteristic slip displacement. Yet these properties of stiff clays and shales have not… read more here.

DOI: 10.1007/s11668-018-0457-x
Abstract: The finite element (FE) predictions of single-bolt connections shear-out failure in the literature were conducted with only elastic–plastic material models without any fracture model. This paper presents the FE single-bolt connection shear-out fracture (SBCSOF) prediction… read more here.

DOI: 10.1016/j.cma.2020.113265
Abstract: Abstract Geologic shear fractures such as faults and slip surfaces involve marked friction along the discontinuities as they are subjected to significant confining pressures. This friction plays a critical role in the growth of these… read more here.

DOI: 10.1038/s41598-018-38437-y
Abstract: Fracture of initially crack-free bodies often occurs due to plastic instabilities known as shear bands. Previous computer simulations advanced a myriad of mechanisms to rationalize shear banding. However, they were restricted to planar geometries. We… read more here.
