Effect of Lamination Angle and Thickness on Analysis of Composite Plate Under Thermo Mechanical Loading

Abstract

Analytical formulation and solution of stress analysis of composite plate subjected to thermo mechanical loading for various ply orientation and thickness of lamina are studied. The main aim of the paper is to investigate how mechanical and thermo mechanical loading would affect the stress ratio and stress distribution of composite plate. The plate is composed of layers of glass-epoxy composite and the orientation of the layers is assumed to be antisymmetric about the neutral axis of the laminate. The plate is subjected to a combined mechanical loading of tensile force and moment along x direction. The thermo mechanical stress is calculated for different ply orientation and thickness ratio, subjected to a temperature change and mechanical loading. The effect of number of lamina and varying thickness of laminate on the stress ratio and stress distribution is studied. The results in this paper are obtained by use of MATLAB Programming and by Finite element software ANSYS 14. Results obtained from both the methods are compared. Such type of loading finds wide application in aircraft flying at high altitude, marine application, medical devices etc.

Analysis of Mechanical Properties of the “Bearing” Part Based on Polished Samples

“…Histogram ( Fig. 2) serves as an input to AntHill TM software which computes off-axis stiffness matrices Q ̅ (see for example [4,5,6] for details) which are later use for evaluating effective engineering constants of each analyzed polished sample. Position of the cross-cuts on "Bearing" part can be seen in Fig.…”

Free Vibration Analysis of Simply Supported P-FGM Nanoplate Using a Nonlocal Four Variables Shear Deformation Plate Theory

“…Functionally graded materials (FGM) can be characterized by the gradual variation of material properties in the thickness. A new type of composite materials is developed recently (Abdelbaki et al [1]; Arnab Choudhury et al [2]; Abdelbaki et al [3]; Ebrahimi and Barati [4]; Ebrahimi and Heidari [5]; Elmerabet et al [6]; Elmossouess et al [7]; Houari et al [8]; Karami et al [9]; Mahjoobi and Bidgoli [10]; Mohamed et al [11]; Mokhtar et al [12]; Mokhtar et al [13]; Sadoun et al [14]; Salari et al [15]; Shafiei and Setoodeh [16]; Shokravi [17]; Tlidji et al [18]; Tounsi et al [19]; Tu et al [20]; Bocko, J et al [21]; Jozef, B et al [22]; Stephan, K et al [23]; Murín, J et al [24]; Sapountzakis, E et al [25]).…”

The Fe Analysis and Variation of Composite Top Hat Shaped Beam

“…The original beam has a prismatic top hat cross section, which is to be replaced with a slightly different geometry, in order to reduce the overall displacement in the model. Two ways of modeling composites are presented and compared (firstly a model with homogenized properties using the rule of mixtures and classical lamination theory [2,3], and secondly a model created with actual lamina). All computations are done for all different types of geometry using the finite element method solver Abaqus.…”
