Abstract: In elasticity theory, a neutral inhomogeneity is defined as a foreign body which can be introduced into a host solid without disturbing the stress field in the solid. The existence of circular neutral elastic nanoinhomogeneities ...

Abstract: Multistable metastructure can be used as a reusable energy-absorbing structure which is usually accompanied by relatively low energy absorption capacity. In this work, a novel structure with variable cross-sectional width ...

Abstract: In the present work, a novel experiment for the flexible piezoelectric system was introduced. The flexible piezoelectric film was spontaneously in contact with the soft substrate conformably. After driven by the pure ...
