Finite element analysis of thermal stress of laminated composite plates using Taguchi method

In present study, thermal stress behavior of laminated composite plates subjected to constant temperature load was investigated using Taguchi method according to von Mises stress. Numerical thermal stress analyses were conducted based on L8 orthogonal array including four control factors with two levels. Fiber orientation angles of laminates for the plates were used to be control factors. Finite element analysis of the plates was carried out using ANSYS software. Fiber angles with optimum levels and their effects on thermal stress of plates were detected using analysis of signal to noise (S/N) ratio. Level of importance of laminates and percentage effect ratio of each laminate on von Mises stress were determined according to analysis of variance (ANOVA).
