A novel 316L stainless steel Vertex Modified BCC (VM-BCC) lattice unit cell with attractive performance characteristics is developed. Lattice structure, as well the sandwich panel, are constructed. Numerical simulation utilized to simulate quasi-static compression, dynamic compression and blast behavior considering rate-dependent properties, elastoplastic response nonlinear contact. Finite element results validated by comparing experimental results. Parametric studies conducted gain insight into effects of loading velocity, equivalent TNT load explosion distance on pattern panel. Testing indicate that proposed VM-BCC structure exhibits more superior plateau stress specific energy absorption (SEA) than those or Octet one. The will provide reference for improving protective efficiency in key equipment fields enhancing overall safety.
