| 英文摘要 | With an exquisite design that allows the elastic modulus to decrease in the surface layer and vary periodically inside, the stomatopod dactyl club can easily penetrate a hard and tough conch shell. Inspired by this idea, in this paper, a surface gradient target and a periodic layered target were designed. The failure processes of the two bionic targets and a uniform target under impact were studied with the finite element method (FEM), and the mechanism that allows the bionic designs of elastic modulus to optimize stress distribution and improve com- patibility of deformation to greatly strengthen impact resistance of the targets was revealed. |
