Mechanical properties in tensile loading of H13 re-entrant honeycomb auxetic structure manufactured by direct metal deposition

Mechanical properties in tensile loading of H13 re-entrant honeycomb auxetic structure manufactured by direct metal deposition

Auxetic materials and structures have a negative Poisson’s ratio. When a tensile load is applied, they become thicker in lateral direction and vice versa. This paper presents a study on the mechanical behavior of a metallic re-entrant honeycomb auxetic structure manufactured by laser assisted Direct...
