The Behavior of Lateral Crushed of Corrugated Composite Plates

An experimental investigation was conducted to compare the crash characteristics and energy absorption capacity of a series of composite plate specimens with different corrugation profiles, these are sinusoidal triangles, and squares with flat composite plates placed at the top and bottom of corrugated plates. All these specimens were fabricated from glass fibers with the hand layup technique. Each profile has three different types of specimens: single plates, double plates, and triple plates. The corrugated plates are fixed over each other and subjected to the same kind of compression load. All these models have been exposed to lateral crushing load and then the collapse of these models has been observed and the results have been recorded. Finally; all the results obtained in this research were recorded and discussed. It is found that the highest value of specific energy of absorption was (1.579 kJ/kg) recorded for the level two square profile specimen. However, the lowest value (0.401 kJ/kg) was recorded for the level one sinusoidal profile specimen.
