The property of concrete is very significant to structural safety, and the early hydration process plays a critical role in the final concrete property. This paper develops a self-emission and detection (SED) principle with a single piezoelectric smart aggregate (SA) transducer, which is used as both an actuator and a sensor, to monitor the concret...

Organisms with self-helix structures are widely found in nature. Four-dimensional (4D) printing have been realized by designing structures and programming deformation of smart materials. This paper presents an innovative method of controlled self-helix structures by designing and fabricating of a bilayer structure with smart material polylactic aci...

The main novelty of this paper is the use of poly-ethylene terephthalate glycol (PETG) as a new shape memory polymer with excellent shape memory effect (SME) and printability. In addition, for the first time, the effect of programming temperature on PETG 4D printed samples has been studied. The amorphous nature of the PETG necessitates that molecul...

Layered or 2-2 configuration magnetoelectric (ME) composites have gained significant interest in the last few decades owing to their ease of fabrication and relatively high ME output realizable at room temperature. Conventionally, layered ME composites are fabricated by bonding the constituent magnetostrictive and piezoelectric layers via an epoxy ...

Auxetic metamaterials attract wide attention due to their unusual mechanical behaviours. This work explores the tunability of the bidirectionally hyperbolic deformation of thin plates under uniaxial compression, instead of the Euler buckling deformation. Inspired by the horseshoe structures, through tuning the radius and thickness of the central ci...

Piezoelectric metamaterials with shunt resonant circuits have been extensively investigated for their tunability in bandgaps. However, the vibration attenuation ability induced by the electromechanical coupling is generally weaker than that of mechanical metamaterials, limiting their applications in engineering practice. This research presents a no...

In this paper, a straightforward procedure is presented for optimal design of negative derivative feedback (NDF) controller with maximum damping and H2 optimization method. NDF is a controller, which works as a band-pass filter, cutting off the control action far from the natural frequencies associated with the controlled modes and reducing spillov...
