Journal of Civil Engineering and Management, 2021 Breakout is a shear failure due to compression that forms around the borehole due to stress concentration. In this paper, the breakout theory model is investigated by combining the equilibrium elasticity equations of stress around the borehole with two ...

Formulation of cross-anisotropic failure criterion for soils
Water Science and Engineering, 2013 Inherently anisotropic soil fabric has a considerable influence on soil strength. To model this kind of inherent anisotropy, a three-dimensional anisotropic failure criterion was proposed, employing a scalar-valued anisotropic variable and a modified ...

Failure Criterion for Brick Masonry: A Micro-Mechanics Approach
Studia Geotechnica et Mechanica, 2015 The paper deals with the formulation of failure criterion for an in-plane loaded masonry. Using micro-mechanics approach the strength estimation for masonry microstructure with constituents obeying the Drucker-Prager criterion is determined numerically ...

Microstructure Based Failure Criterion For Ductile Materials
EPJ Web of Conferences, 2018 For ductile metals, the process of dynamic fracture occurs through nucleation, growth and coalescence of voids. The stress required to nucleate these voids is inferred from the velocimetry data (using the acoustic approach) and termed as the spall ...

Optimization of laminates subjected to failure criterion [PDF]
Metalurgija, 2011 The paper is aimed on laminate optimization subjected to maximum strain criterion. The optimization problem is based on the use of continuous design variables. The thicknesses of layers with the known orientation are used as design variables.

Finite Element Simulation of Multi-Scale Bedding Fractures in Tight Sandstone Oil Reservoir
Energies, 2019 Multi-scale bedding fractures, i.e., km-scale regional bedding fractures and cm-scale lamina-induced fractures, have been the focus of unconventional oil and gas exploration and play an important role in resource exploration and drilling practice for ...

Towards the Analysis of Reliability Index of Steel Frame Equipped with TADAS Yield Damper
Tehnički Glasnik, 2023 During an earthquake, a considerable amount of kinetic energy from the ground acts as a lateral force on the structure, and this energy causes damage to the main components of the structure, including beams, columns and joints.
