this paper presents an exact analytical solution for two-dimensional conductive heat transfer in spherical composite pressure vessels .the vessels are in spherical shape and fibers are winded in circumferential direction. the analytical solution is obtained under the general boundary conditions which consist of convection, conduction and radiation inside/outside of vessel. the heat transfer equ...

Buildings made using cross-laminated timber have become widespread over the last decade. The experience of designing and operating such buildings various functional purposes confirms expediency their construction use. This article provides a solution to problem modeling calculating panel houses finite element method given mechanical characteristics material. possibility with use flat elements, ...

Title of Dissertation: CHARACTERIZATION, MODELING, AND OPTIMIZATION OF POLYMER COMPOSITE PIN FINS Raj Bahadur, Doctor of Philosophy, 2005 Directed By: Professor, Avram Bar-Cohen, Mechanical Engineering Increasing electronic product manufacturing volumes and cooling requirements necessitate the use of new materials and innovative techniques to meet the thermal management challenges and to contri...

Natural fibers are promising for engineering applications due to their low cost. They are abundantly available in tropical and subtropical regions of the world, and they can be employed as construction materials. Among natural fibers, bamboo has been widely used for housing construction around the world. Bamboo is an optimized composite material which exploits the concept of Functionally Graded...

This paper reports a method that numerically models the deformation and accumulation of hidden damage in structural elements are an inhomogeneous thermal field exposed to radiation. Materials considered those exhibiting orthotropy (transversal isotropy) long-term properties. The problem is stated as boundary – initial value one. To solve it, finite element initial-difference time integration us...

A new approach for analyzing cracked problems in 2D orthotropic materials using the well-known element free Galerkin method and orthotropic enrichment functions is proposed. The element free Galerkin method is a meshfree method which enables discontinuous problems to be modeled efficiently. In this study, element free Galerkin is extrinsically enriched by the recently developed crack-tip orthot...

The paper demonstrates improved structural low-frequency vibroacoustic performance of cross-laminated timber (CLT) floor panels by informed selection the wood material. use species and strength classes that are not traditionally assigned to CLT was investigated in order study their influence on dynamic characteristics response metrics. potential each orthotropic material properties alternate vi...
