NUMERICAL SIMULATION OF TRANSIENT STRESS WAVES IN ELASTIC HALF PLANE WITH A RECTANGULAR CAVITY WHILE CENTERING THE VERTICAL EXPLOSIVE IMPACT
Abstract
The paper provides some information modeling safety elastic half plane in the case of non-stationary wave explosive impact using the finite element method. Considered the wave theory of explosive safety. Applicable technical tool in the form of vertical rectangular cavities to increase the security of the object when focused vertical explosive impact. The explicit two-layer scheme. Reviewed the problem statement with the cavity (ratio of width to height of one to four) in a half-plane when exposed in the form of Delta functions. Solve the system of equations of 59048 unknown. Explosive impact is modeled as a triangular pulse. Five points is a change in the grid voltages.
