Numerical modeling of the process of high-velocity penetration of an obstacle. (Russian)
Authors: Rîbachin Boris
Abstract
The paper gives formulation of problems in two-dimensional flow for high velocity impact. The numerical solution of this problems is obtained by modified big particles method. Modification consists of distinguish and following of contact and free boundaries. The statement of the numerical modelling problem and numerical results are presented. It is show that the values crater derpth are in a good agreement with experimental values for spherical shape indentor.Contents
