Prediction of Crack Initiation Direction for Inclined Crack Under Biaxial Loading by Finite Element Method
This paper presents a simple method based on strain energy density criterion to study the crack initiation angle by finite element method under biaxial loading condition. The crack surface relative displacement method is used to eliminate the calculation of the stress intensity factors which are normally required. The analysis is performed using higher order four node quadrilateral element. The...
متن کاملContact Problem for Bonded Nonhomogeneous Materials under Shear Loading
The present paper examines the contact problem related to shear punch through a rigid strip bonded to a nonhomogeneous medium. The nonhomogeneous medium is bonded to another nonhomogeneous medium. The strip is perpendicular to the y-axis and parallel to the x-axis. It is assumed that there is perfect bonding at the common plane surface of two nonhomogeneousmedia. Using Fourier cosine transforms...
متن کاملRegulation of Kir2.1 Function Under Shear Stress and Cholesterol Loading
L ining the innermost layer of blood vessels, the endothelium is in direct contact with circulating blood elements and, consequently, is affected by mechanical forces generated by blood flow. Among these forces, fluid shear stress site-specifically regulates endothelial cells (ECs): In regions where the flowing blood is multidirectional (low shear stress or disturbed flow), ECs are activated an...

برد عددی ماتریس مربعی a را با w(a) نشان داده و به این صورت تعریف می کنیم w(a)={x8ax:x ?s1} ، که در آن s1 گوی واحد است. در سال 2009، راسل کاردن مساله برد عددی معکوس را به این صورت مطرح کرده است : برای نقطه z?w(a)، بردار x?s1 را به گونه ای می یابیم که z=x*ax، در این پایان نامه ، الگوریتمی برای حل مساله برد عددی معکوس ارانه می دهیم.
15 صفحه اولDeflection of a hyperbolic shear deformable microbeam under a concentrated load
Deflection analysis of a simply supported microbeam subjected to a concentrated load at the middle is investigated on the basis of a shear deformable beam theory and non-classical theory. Effects of shear deformation and small size are taken into consideration by hyperbolic shear deformable beam theory and modified strain gradient theory, respectively. The governing differential equations and c...
