A three dimensional geometrical model for calculation of induced stresses surrounding longwall working
There are various criteria that need to be examined alongside each other when designing a longwall mining system. Challenges such as determination of the supported roof width, support system design, caving height determination, lateral or chain pillar size determination, and optimum support design for the main gate and tail gate roadways have to be tackled for this aim. Three-dimensional analys...
متن کاملA three-dimensional calculation of atmospheric neutrinos
A Monte-Carlo calculation of the atmospheric neutrino fluxes [1, 2] has been extended to take account of the three-dimensional (3D) nature of the problem, including the bending of secondary particles in the geomagnetic field. Emphasis has been placed on minimizing the approximations when introducing the 3D considerations. In this paper, we describe the techniques used and quantify the effects o...
متن کاملThrough-tiiickness Elastic Constant for Aramid-epoxy/aluminum Composite Materials*
The objectives in this study were to deterrnine the through-thickness elastic constant of fiber-epoxy/metal composites with ultrasonic measurements and determine the elastic constants of the constituent layers. The specimens that we studied consist of alternaring layers of aluminum (2024 TI) and fiber-epoxy [1], all of which are 200 to 300 jlm thick. As Figure 1 indicates the outer two layers o...
متن کاملA New Three-Dimensional Refined Higher-Order Theory for Free Vibration Analysis of Composite Circular Cylindrical Shells
A new closed form formulation of three-dimensional (3-D) refined higher-order shell theory (RHOST) to analyze the free vibration of composite circular cylindrical shells has been presented in this article. The shell is considered to be laminated with orthotropic layers and simply supported boundary conditions. The proposed theory is used to investigate the effects of the in-plane and rotary ine...
متن کاملThree-Dimensional Interfacial Green’s Function for Exponentially Graded Transversely Isotropic Bi-Materials
By virtue of a complete set of two displacement potentials, an analytical derivation of the elastostatic Green’s functions of an exponentially graded transversely isotropic bi-material full-space was presented. Three-dimensional point-load Green’s functions for stresses and displacements were given in line-integral representations. The formulation included a complete set of transformed stress-p...
