Stress wave transmission and reflection through auxetic solids

摘要

This paper establishes the effect of auxeticity on stress wave transmission and reflection. Specifically, investigation was made on wave transmission across two perfectly bonded isotropic solids in which the Poisson's ratios ranged between -1 and 0.5. The results show that the combined use of auxetic and conventional solids at extreme Poisson's ratio is helpful to multiply or even to eliminate stress waves, under the prescribed density and modulus relations. These results suggest the usefulness of auxetic solids as smart materials and in smart structures for effective control of stress wave transmission.
