Lamb wave propagation in negative Poisson's ratio composites

Research output: Chapter in Book/Report/Conference proceedingConference Contribution (Conference Proceeding)


Lamb wave propagation is evaluated for cross-ply laminate composites exhibiting through-the-thickness negative Poisson's ratio. The laminates are mechanically modeled using the Classical Laminate Theory, while the propagation of Lamb waves is investigated using a combination of semi analytical models and Finite Element time-stepping techniques. The auxetic laminates exhibit well spaced bending, shear and symmetric fundamental modes, while featuring normal stresses for A(0) mode 3 times lower than composite laminates with positive Poisson's ratio
