It is the first and unique research laboratory in Turkey, associated with defense industries and is also called DTM-Lab -- DTM-Lab was founded in 2007 after a project entitled "New integrated armor design: development and optimization of alternative interface materials" and supported by the Department of the Development and Planning of the Turkish Government (DPT) as guided project -- The project aimed the use of foam materials as interlayer material in integrated armor structures

10th Biennial Conference on Engineering Systems Design and Analysis, ESDA 2010; Istanbul; Turkey; 12 July 2010 through 14 July 2010 ; Today, it is imperative that armored vehicles need advanced protection kits against anti-symmetric threats more than before. The primary goal of this study was to assess benefits of explicit hydrocodes for mine protection resistance of armored vehicles. An analysis of an armored vehicle under blast loading caused by high explosive (HE) detonation is presented with comparison to a full-scale test. The problem was examined using LS-DYNA which is an explicit non-linear finite element code. Multi Material Arbitrary Lagrangian Eulerian (MM-ALE) Fluid Structure Interaction Method was selected to model the explosion domain so as to observe advancing of the shock wave in the compressed air and to investigate the effects of blast on the vehicle structure after explosion. Johnson-Cook constitutive material model, Jones-Wilkins-Lee (JWL) and Linear Polynomial equation of states were used for the problem. Results show that numerical analysis was in good agreement with the experimental result.
