The weak stiffness and strength of materials with negative Poisson's ratio limits their application. In this paper, three types of novel lattices with negative Poisson's ratio are proposed to improve not only stiffness and strength but also energy absorption capacity by embedding different ribs into a classic re-entrant structure. Unit cell analyses show these novel lattices have significantly increased Young's modulus along the loading direction, and Type C can maintain sufficient negative… CONTINUE READING
