Solving three-dimensional problems in natural and hydraulic fracture development : insight from displacement discontinuity modeling
… is strongly influenced by the spacing-to-height ratio of fractures, as well as the differential stress magnitude. We show that the angle of intersection between two non-coincident but parallel en-echelon fractures depends strongly on the fracture height-to-spacing ratio, with intersection angles …

Pore fluid pressure detection within the plate boundary fault interface of the Costa Rica convergent margin using AVO attributes
… plates. We applied pre-stack Kirchhoff time migration to a subset of these data across the frontal prism where amplitude versus offset (AVO) attributes were extracted along the decollement. When pore fluid pressure, l , exceeds 0.7, the pressure at which Poisson’s ratio begins to approach that …

Design, modelling and development of origami-inspired tubular compliant mechanisms towards radially closable applications
… Their bistable characteristics, negative Poisson's ratio, and tunable stiffness have found wide application in fields such as aerospace, medical devices, and robotics. However, their potential for radial closability remains unexplored. This study identifies the similarity between the …

Comparison and Correction of Multistage Triaxial Tests to Single Stage Triaxial Test for the Rock Mechanical Testing
… the results in terms of Young’s modulus, Poisson’s ratio, stiffness, friction angle, and cohesion. We provide a detailed discussion of the techniques and measurements required to correct the MST results to those obtained from SST protocol. A single correction factor is found to relate the …
