WebbIn this article, an analytical model based on theory of elasticity is presented to find the breakout failure area around the inclined boreholes. Mogi-Coulomb shear failure criterion is used, in which there is also the effect of the intermediate principal stress. WebbTheories of Failure Strength of a material or failure of the material is deduced generally from uni-axial tests from which stress strain characteristics of the material are obtained. The typical stress-strain …

WebbThe paper deals with the issue of modelling elastic wave propagation using the discrete element method (DEM). The case of a longitudinal wave in a rod with a circular cross-section was considered. A novel, complex algorithm consisting of the preparation of models and simulation of elastic waves was developed. WebbTheory of Elastic Failure.

"Material failure theory is an interdisciplinary field of materials science and solid mechanics which attempts to predict the conditions under which solid materials fail under the action of external loads. The failure of a material is usually classified into brittle failure (fracture) or ductile failure (yield). Depending on the … Visa mer In materials science, material failure is the loss of load carrying capacity of a material unit. This definition introduces to the fact that material failure can be examined in different scales, from microscopic, to macroscopic. … Visa mer A yield criterion often expressed as yield surface, or yield locus, is a hypothesis concerning the limit of elasticity under any combination of … Visa mer Material failure can be distinguished in two broader categories depending on the scale in which the material is examined: Microscopic failure Microscopic material … Visa mer Failure of brittle materials can be determined using several approaches: • Phenomenological failure criteria • Linear elastic fracture mechanics Visa mer • Fracture mechanics • Fracture • Stress intensity factor • Yield (engineering) Visa mer " - Theory of elastic failure
