Abstract :This statistical and numerical study deals with buckling temperature behavior of laminated composite plates with central circular and semicircular holes. Numerical buckling temperature analyses were performed using finite element software ANSYS based on Taguchi L18 orthogonal array. The plates were designed from graphite/epoxy systems. Fiber orientation angles and cutout shapes of the plates were assumed to be the control factors. Analysis of signal-to-noise ratio was used in order to investigate of the effects of fiber orientation angles and cutout shapes on the critical buckling temperature of the plates. Also, analysis of variance was performed in order to see percentage contribution rates and significance levels of control factors.
