In this study, the effect of fiber orientations on natural frequencies hybrid composite laminate (HCGFRE) that is consisted sequential stacking plain woven carbon reinforced epoxy (CFRE) and glass (GFRE) fibers was investigated. A finite element approach carried out in order to determine laminate. Analyzes were performed using LS-DYNA® software. analysis, corresponding first three modes determi...

Abstract The reduction of weight elements is considered as a major objective several manufacturing companies. This will help in growing application sections the used fiber composites for important structural elements. Modern metal laminate (FML) having lightweight properties established to be instead other substances different applications including those related aerospace industrial sector. Fi...

The concept of “curved perspective” has been used by artists such as M.C. Escher in order effectively convey a sense of three dimensional space while being restricted to a two dimensional canvas. We present an interactive system to create and manipulate projections with a curvilinear perspective. Our system presents the user with a set of intuitive screen-space perspective primitives that contr...

The first form of damage in composite laminates is often matrix microcracks that are defined as intralaminar or ply cracks across the thickness of the ply and parallel to the fibers in that ply (see reviews in [1,2]). Tensile loading, fatigue loading, environment, and thermal cycling can all lead to microcrack formation. Microcracks can form in any ply that has a significant component of the ap...

The aim of this work is to investigate analytical (Classical theory) and [ANSYS Parametric Design Language (APDL)] analysis laminate composite plate. free vibration with two boundary conditions simply supported (SSSS) & clamped ends (CCCC) are taken into account in work. equations motion that governs the predication dynamic behavior cross angle ply solved theoretically using [Matlab] softwa...

In this work, transient dynamic stress concentration in a hybrid composite laminate subjected to a sudden internal crack is examined. It is assumed that all fibers lie in one direction and the applied load acts along direction of fibers. Two types arrangements are considered for the fiber; square and hexagonal arrangement. Using shear lag model, equilibrium equations are deduced and upon proper...

re-establishing a patient’s lost dental esthetic appearance is one of the most important topics for contemporary dentistry. new treatment materials and methods have been coming on the scene, day by day, in order to achieve such an aim. most dentists prefer more conservative and aesthetic approaches, such as direct and indirect laminate veneer restorations, instead of full-ceramic crowns for ant...

Unlike well-investigated polymer-based soft actuators such as gel, Ionic Polymer-Metal Composite, conducting polymer, a CFRP-based polymeric laminate possesses quite distinguished properties. It was previously reported that a CFRP-PVC laminate exhibited two-way deflection in accordance with environmental temperature, but it could not exhibit symmetric deflection because of its asymmetric struct...

The effect of boundary conditions on the vibrations variable stiffness composite laminates (VSCL) with curvilinear fibers is particularly interesting because fiber orientations at plate edges and in plate’s domain can differ. Since real boundaries are not ideal limit cases usually assumed literature, a more correct model be achieved by representing as elastically restrained edges. This approach...
