... are practically realizable using piezoelectric structures with shunting circuits [ 18 , 44 – 46 ] and thus could serve as a versatile platform to implement the directional energy transfer control of elastic waves. The time-reversal symmetry is broken in time-modulated media, which thus no longer respects...

.... This result is used to study the uncoupling of general linear multi-degree-of-freedom (MDOF) structural and mechanical systems described by arbitrary damping and stiffness matrices through quasi-diagonalization, and real orthogonal coordinate transformations. The uncoupling leads to independent subsystems...

... and curved pleated structures, introduce the additional complexity of mechanical coupling between the folds. This coupling can be exploited to obtain morphing structures with more robust folding pathways. We discuss one-degree-of-freedom mechanisms and folds actuated by spontaneous curvature (as in the case...

Similar self-contact localized solutions have also been reported in rods subjected to simultaneous twist and tension [1]. To investigate localized...

... symmetries of the parent and product phases obey no group-subgroup relation [1; 2; 3]. RMTs include most famously, for simple Bravais lattices, the bcc-fcc structural transition taking place in many metals, alloys, and minerals, of great importance in science and technology [4]. We focus on the case of RMTs...
