Experimental and Numerical investigation on CK45, St12, Al3105 with layers under drop test free loading

In this investigation, the Al sheet metals Al3105, Ck45 and St12 with layers under impact drop test free loading are tested experimentally and numerically. The sheets are tested with 3-layers under impact free loading numerically. for comparing, the experimental test is tested. The height is 12 cm with free impact loading. The dimention of specimens are 220*230 cm2. with screw the specimens are tied. The fixure are maded with steel and the specimens are fixed on the ficture freely. The screew has Din933 standard. The acceleration data are repoted with accelareation sensor. The deformation are reported with hammer test. Also with theoretical method, the shells are invetigated with the dynamic equations. For numerical modeling, the ABAQUS is used. The resualts are shown that two method are the same resulats. Also the resualts are shown that the energy absorption is more for Al3105-St12-Al3105 to other sheets. Also the acceleration is more for Ck45-St12-Ck45 to other sheets.
