Abstract

The elastic properties of a cracked cellular structure of close-to-zero Poisson’s ratio with trapezoidal beams are studied by the finite element method in this paper. The effects of the crack length and crack angle on the non-dimensional equivalent modulus, including elastic moduli in the x-direction, y-direction, and the shear moduli are analyzed. The numerical results indicate that the degree of reduction in the non-dimensional equivalent modulus due to the crack depends on the crack angle and length.
