Deflection Analysis of Laminated Clamped Rectangular Composite Plates

Numerically investigating the effects of fiber orientation angles and control factors which is an important factor for minimize the deflection of laminated composites. This paper aims to observe the deflection analysis of laminated rectangular plates subjected to cantilever-type loading. The plates are made up of Glass fiber reinforced polymer composite (GFRP). The plates are having 12 plies, are subjected to self-weight, and are analyzed using different orientation angles by using the finite element method. Taguchi’s L9 orthogonal array is being used to obtain different orientation angles of fiber and arrangements. The orientation angle for 3 control factors varies between (10° to 90°) and for 4 control factors between (7.5° to 90°). The Signal to Noise (S/N) ratio is used to estimate the optimum levels for minimum deflection value of control factors. Analysis of variance (ANOVA) is performed for analysing the responses which have powerful influential control factors and their percentage contribution.
