Effect of Couple Stresses on the Stress Intensity Factors for Two Parallel Cracks in an Infinite Elastic Medium under Tension
Stresses around two parallel cracks of equal length in an infinite elastic medium are evaluated based on the linearized couple-stress theory under uniform tension normal to the cracks. Fourier transformations are used to reduce the boundary conditions with respect to the upper crack to dual integral equations. In order to solve these equations, the differences in the displacements and in the ro...
متن کاملValidation of Crack Interaction Limit Model for Parallel Edge Cracks Using Two-dimensional Finite Element Analysis
Shielding interaction effects of two parallel edge cracks in finite thickness plates subjected to remote tension load is analyzed using a developed finite element analysis program. In the present study, the crack interaction limit is evaluated based on the fitness of service (FFS) code, and focus is given to the weak crack interaction region as the crack interval exceeds the length of cracks (b...
متن کاملParallel and Perpendicular Lamellae on Corrugated Surfaces
We consider the relative stability of parallel and perpendicular lamellar layers on corrugated surfaces. The model can be applied to smectic phases of liquid crystals, to lamellar phases of shortchain amphiphiles and to lamellar phases of long-chain block copolymers. The corrugated surface is modelled by having a single q-mode lateral corrugation of a certain height. The lamellae deform close t...
متن کاملA boundary element analysis of crack-propagation mechanism of micro-cracks in rock-like specimens under a uniform normal tension
In this work, the mechanism for fracture of brittle substances such as rocks under a uniform normal tension is considered. The oriented straight micro-cracks are mostly created in all the polycrystalline materials resulting from the stress concentrations. The present work focuses on the interactions of the pre-existing micro-cracks, which can grow and propagate within a rock-like specimen. The ...
متن کاملNumerical Study of Interaction of Two Plane Parallel Jets
In the present work, a numerical simulation of two parallel turbulent jets was performed. The simulations were carried out by using the standard, the standard and the RSM models. A parametric study was also presented to determine the effect of the nozzles spacing and velocity ratio on the axial and transverse positions of the merge and combined points. Correlations between the various paramet...
