Abstract
Steel sheets are used in various industries such as automotive, aerospace, and … . The issue
of impact and penetration in steel sheets has been the main focus of many studies. In this
study, Laboratory and numerical studies of flat and reinforced steel sheets by steel
reinforcement have been performed under the of impact caused by free fall of the weights.
Steel sheets used are steel St12. The material and thickness of the pendentive used are similar
to the sheet and have a width of 2 cm. The parameters have evaluated include the amount of
impact acceleration on the sheet, the rate of permanent deformation, and the amount of energy
absorption for simple and reinforcer flat sheets. The numerical modeling of Abaqus finite
element software is used. The results show that the use of reinforcer causes a slight increase
in the acceleration of the sheet and a significant reduction in its permanent deformation.
