The project's objective is to study the properties and features of a structure damaged under raengkra inserts a Double Hat, bending steel forming a hat off workpieces. There is a fold up the format hat off and splice together and connected by an electric arc, stick together. Workpiece has a different size t 3 values include 1mm., 2mm., 2.5 mm. test portion is a test under bending, which is to insert a raengkra test using Impact Testing Machine by using the height test is 2.14 m. weight of the mass in the hammer is 54 kg. let down by slash, the insertion of Marrakech.Well the place is being increased from three point test results found that the work piece is thick. 2.5 mm. with maximum strength. As part of the analysis of the Finite Element modelling Analysis using Abaqus program by mass, size 54 kg, press down on the piece of work. with a 6.47 m/s velocity work. as increased three point same. trial found that the work piece is thick. 2.5 mm. with a maximum voltage of three shuttles. Comparison between Finite Element Analysis with experiments found that the difference between 1% and the energy absorption analysis found that the thickness of the structure. 1 mm., which has the ability to see the energy up to the load graph will have values below the workpiece. 2.5 mm. However, a corrupted format of a work piece surface the most absorbing energy, has the most value and the appearance of corruption of every piece to save with a high speed camera and displays it in the report.
