Analysis of the War Documents proves that flat hulls with thin-walled steel cannot resist against Anti-Tank Mines. In Recent years, development of V-shape Hull configurations Consider as an efficient Approach to improve Safety of armored vehicles. In the new generation of Armor Vehicle, Monocoque chassis combined with V-shape hull, But Replacement of All of the Old Armor Vehicle in the Defense Industry is not cost effective. So, there is an urgent need to develop the efficient strategy for enhancing the protection level of old armor vehicle. Since most of the armored vehicles used in the armies of different countries were designed and built in the past years, it is very likely that the safety standards have not been fully observed in them. Therefore, it is of great importance to provide a simple and low-cost plan for the reliable upgrade of such armored and logistics vehicles. In this article, by investigating the effect of placing V-shaped composite panels in three case studies, we were able to reduce the acceleration of the center of mass of the passenger compartment by approximately 7 times, in addition to reducing displacement by 50% on average.</span></span></span></span> <span style="font-size:12.0pt"><span style="line-height:150%"><span new="" roman="" style="font-family:" times=""><span style="color:black">In addition, the explosion products were not able to penetrate into the cabin.</span></span></span></span><span style="font-size:12.0pt"><span style="line-height:150%"><span style="font-family:"Times New Roman",serif"></span></span></span></span></span></span></span></span></pre> </div> Ceramic composite, Armor vehicle, Mine explosion, Johnson-Cook material model 4256 4267 http://ase.iust.ac.ir/browse.php?a_code=A-10-780-1&slc_lang=en&sid=1 mustafa mirtabaee mirtabaee_58@yahoo.com 180031947532846004198 180031947532846004198 No Imam Ali Army Officer University mohammad abasi mo.abasi117@gmail.com 180031947532846004199 180031947532846004199 Yes IUST
