Experimental investigation of the crushing behavior of sandwich panel with egg box coremade of corrugated strips abstract

This research investigates the amount of energy absorption in a sandwich panel with a corrugated core ofan egg comb with two different dimensions. Sandwich panels with different core shapes are widely used in thetransportation industry due to their light weight, and many studies have been conducted on its properties, one of whichis the study of energy absorption. Investigating the amount of energy absorption in these types of cores will help toincrease the safety of the passengers. In this research, the cores with the ratio of the angle of the leg to the base of 30degrees (T30) and 40 degrees (T40) were made through sheet cutting and bending and were connected to each otherusing spot welding. ST 37 steel sheet was used for core and surface. The samples were subjected to quasi-staticuniform load. The force-displacement curves were obtained and the peak force value, energy absorption rate, specificenergy absorption and energy absorption efficiency were calculated from the crushing behavior of the sample. It wasfound that the angle ratio has an effect on the amount of energy absorption. The amount of energy absorption in T40was about 1.5 times that of T30 model.
