Effect of Temperature on Damage Identification of Laminated Composite by Means Numerical Methods

Abstract

This study aims to examine the effect of temperature on damage detection in laminated composite materials. In this context, a carbon-reinforced composite plate with [0/90]s stacking sequence is modeled as intact and delaminated by the finite element method. The dimensions, thicknesses, materials used, and stacking sequences of the plates modeled as intact and delaminated are the same. The delamination in the delaminated plate is modeled as the gap in the middle of the plate. These modeled plates were analyzed at different temperature values between -50oC / +50oC. The natural frequencies, mode shapes, and modal curvatures of the plate were obtained by modal analysis. The variation of these data obtained with temperature was examined and the effect of temperature on these data was compared. According to the analysis results, it was observed that the effect of temperature on natural frequency values and modal curvature values was similar to the effect of delamination. The decrease in natural frequencies and the changes in modal curvatures due to delamination occurred with the increase in temperature even in the absence of delamination.
