abstract = {This study examines shaped charge penetration mechanics in steel targets through integrated experiments and simulations. Controlled detonation tests on 35MnB/1045 steel plates (18-40mm) with Cu, Pb, and Pb-Sb liners were combined with LS-DYNA's coupled Eulerian-Lagrangian modeling. Key findings reveal: 1) Penetration depth follows parabolic growth with charge density until cutting-dominated failure initiates at 200 g/m; 2) A critical 17 mm standoff maintains stable penetration, beyond which depth reduces 18.7%/mm, while thinning plates from 40 mm to 20 mm increases penetration by 62.3% via shear-bending failure; 3) Pb-Sb liners achieve 14.4% deeper penetration (58.0 mm) than Cu through optimized impedance properties, with dual-strand designs enhancing depth 38.8% via cumulative jet effects. Numerical validation identifies 0.5-0.8 GPa jet pressure thresholds (89-93% energy dissipation) aligned with microstructural evidence. The results demonstrate that material selection (Pb-Sb alloys) and geometric optimization (dual-strand configurations) significantly improve demolition efficiency.}
