The present paper deals with the mixed mode fracture analysis of a weakened orthotropic half-plane with multiple cracks propagation. The orthotropic half-plane contains Volterra type glide and climb edge dislocations. It is assumed that the medium is under in-plane loading conditions. The distributed dislocation technique is used to obtain integral equations for the dynamic problem of multiple ...

In this paper, free vibration analysis of orthotropic functionally graded material (FGM) cylinders was carried out by a Mesh-Free method. In this analysis, moving least squares shape functions are used for approximation of displacement field in the weak form of equilibrium equation. Essential boundary conditions are imposed by transformation method. In this simulation, an axisymmetric model is ...

An obvious visual feature of wood structure in many coniferous species, and especially pines, is the presence of annual growth rings. The growth rings are not completely uniform in width and often provide a record of weather and climate-based events that had an impact on growth. These events have impacts on the formation of the tapered cylindrical layer of earlywood in the early part of the gro...

Additive manufacturing is becoming one of the most utilized tools in an increasing number fields from Industry 4.0 concepts, engineering, and to aerospace medical applications. One important issue with additive-manufactured components their orthotropic behaviour where mechanical properties are concerned. This due layer-by-layer process particularly hard predict since it depends on a factors, in...

Room-temperature (RT) mechanical anisotropy limits the broad applications of wrought magnesium (Mg) alloys. To weaken anisotropy, here, we proposed a design idea to create mixed texture. In present study, successfully fabricated Mg-3Y/Mg-5Li (W3/L5, wt.%) laminated composite, having texture with closely orthotropic shape, consisting an ED-split component in W3 layer and TD-split L5 layer, via b...

An experimental study of the stress distribution around holes in orthotropic composite laminates has been conducted using thermoelastic stress analysis (TSA). Quantitative thermoelastic studies of stress concentrations in metallic plates is a straightforward matter, all that is required is the ratio of the response from the hole and a far-field reading. For orthotropic materials the situation i...

For the purpose of identifying the sound transmission characteristics of honeycomb sandwich panels that are commonly used in aircraft industries, Finite Element Method (FEM) combined with Boundary Element Method (BEM) has been widely used. However, the latter approach is not always applicable to high frequency analysis since it requires a large number of FEM/BEM meshes resulting in high computa...
