Experimental investigation of penetration performance of shaped charge into concrete targets
TL;DR: In this article, the authors explored the penetration performance of shaped charges with different cone angles and liner materials into concrete targets by means of experiments and compared the penetration process and the destruction mechanism of concrete targets.

A numerical method based on fully discrete direct discontinuous Galerkin method for the time fractional diffusion equation
TL;DR: An implicit fully discrete direct discontinuous Galerkin (DDG) finite element method is considered for solving the time fractional diffusion equation and it is proved that the scheme is stable and the energy norm error estimate is convergent.

High Order Positivity- and Bound-Preserving Hybrid Compact-WENO Finite Difference Scheme for the Compressible Euler Equations
TL;DR: An improved hybrid scheme employing the nonlinear 5th-order characteristic-wise WENO-Z5 finite difference scheme for capturing high gradients and discontinuities in an essentially non-oscillatory manner and the linear 5 fourth-order conservative compact upwind (CUW5) scheme for resolving the fine scale structures in the smooth regions of the solution in an efficient and accurate manner is developed.

Jet formation and penetration mechanism of W typed shaped charge
TL;DR: In this article, a new variant of shape charge, named W typed shape charge (WSC), is proposed, which can meet the demand of 1:1 ratio, and is based on the geometry that can produce annular jets upon proper initiation scheme.
