stress intensity factors

This work considers the sensitivity analysis of the couple stress hybrid nanofluid flow (mixture of methanol-base fluid and AA7072-AA7075 hybrid nanoparticles) subjected to a stretching surface with magnetic field (MHD) effect.  The boundary layer and energy equations are simplified and then solved using the bvp4c solver embedded in the Matlab software.  The validation is conducted with the previously published results indicating that the present model is correct.  The numerical results highlight the effect of the physical factors like magnetic parameter, nanoparticle's

In this paper, the derivation of hyper-singular integral equations (HSIEs) for thermoelectric bonded materials (TEBM) featuring a crack parallel to interface subject to in-plane shear stress $\tau^\infty_{xy}$ was intensively studied.  Generally, stress intensity factors (SIFs) were calculated using HSIEs with the help of modified complex stress variable function (MCSVF), and continuity conditions of the resultant electric force and displacement electric function.  The unknown crack opening displacement (COD) function, electric current density, and energy flux load are

Purpose. A two-dimensional mathematical model for the problem of elasticity theory in a three-component plate containing rectilinear crack due to the action of mechanical efforts is examined. As a consequence, the intensity of stresses in the vicinity of tops of the crack increases, which significantly affects strength of the body. This may lead to the growth of a crack and to the local destruction of a structure.

Purpose. A two-dimensional mathematical model for the problem of elasticity theory on joined dissimilar elastic half-planes containing rectilinear crack under the action of mechanical efforts on the shores of a crack is examined. As a consequence, the intensity of stresses in the vicinity of tops of the crack increases, which significantly affects strength of the body. This may lead to the growth of a crack and to the local destruction of a structure.
