The Effect of Impact Energy in Anisotropic Sandwich Plate

Abstract

The effect of anisotropic property in plates is very efficient in impact energy, recently the sandwich plates have been developed in order to reduce the weight of mechanical part and reduce the applied load in plastic forming. In this paper the effect of anisotropic property in izod impact energy for steel , aluminum and sandwich plates have been studied experimentally. Experimental results showed that the maximum value of impact energy at specimen with rolling direction(0º) and the minimum impact energy at specimen (90º)direction normal to rolling directing while the impact energy at specimen (45º) was found to be in between (0º) and (90º) . Result also showed that the effect of temperature in izod impact energy is increase as the impact energy increase with neglect any significant change in anisotropic property. Also it has been found that increase the thickness of specimen would increase izod impact energy.
