Mechanical properties of materials have long been one of the most fundamental and studied
areas of materials science for a myriad of applications. Recently, mechanical metamaterials …

Materials that become thicker when stretched and thinner when compressed are the subject
of this review. The theory behind the counterintuitive behavior of these so‐called auxetic …

Composites with extremal or unusual thermal expansion coefficients are designed using a
three-phase topology optimization method. The composites are made of two different …

Auxetic materials exhibit the very unusual properties of becoming wider when stretched and
narrower when squashed [1], that is they have negative Poisson's ratios. Apart from the pure …

Poisson's ratio is, for specified directions, the ratio of a lateral contraction to the longitudinal
extension during the stretching of a material. Although a negative Poisson's ratio (that is, a …

Although a negative Poisson's ratio (that is, a lateral extension in response to stretching) is
not forbidden by thermodynamics, for almost all common materials the Poisson's ratio is …

The application of conducting polymers for the direct conversion of electrical energy to
mechanical energy in electromechanical actuators is analyzed using theoretical and …

The current status of research into auxetic (negative Poisson's ratio) materials is reviewed,
with particular focus on those aspects of relevance to aerospace engineering …
