An investigation on buckling behavior of simply supported woven steel reinforced thermoplastic laminated plates with lateral strip delamination

The effects of the lateral strip delamination width on the buckling loads of the simply supported woven steel reinforced thermoplastic laminated composite plates have been investigated. The mechanical properties of the manufactured composite layers have been measured. Three-dimensional finite element models of the square laminated plates have been established. Each of these models possesses four layers and a different delamination width between the second and third layers. The orientation angle of the fibers is chosen as 0, 15, 30 and 45degrees. The buckling loads have been determined for each model having different lateral delamination width. The results show that important decreases in the buckling loads occur after a certain value of the delamination width. The variation ratios of the results of the symmetric or antisymmetric cases are approximately the same for each angle.
