Abstract

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).
