In this paper the deformation of a concave disc in real configuration in an antitank mine is analyzed al well as its effect on armor vehicles. The disc is modeled by three-dimensional finite elements DYNA3D in the software. The deformation of the disc by the influence of detonation products is monitored in time sequences. https://atzbota8hcqy.collectblogs.com/79712208/infodemia-rumores-fake-news-mitos
