In this paper, an open-cell metallic foam was filled in by a tough shape memory polymer (SMP), to form a hybrid metal/polymer composite with multifunctionalities and enhanced mechanical properties. This work aims to study the positive composite actions between the metallic skeleton and the SMP filler. Mechanical, thermal, and conductive properties ...

An inertial impact locomotion robot (IILR), consisting of a base, three supporting feet and four vertically distributed piezoelectric bimorph actuators (PBAs), was developed in this work. The IILR could complete plane locomotion with three degrees of freedom (DOFs), including translation along X-axis, translation along Y-axis and rotation around Z-...

Carbon fibre reinforced plastic (CFRP) materials are of interest for the aerospace and aviation industry to master growing economic and ecological challenges. In contrast to conventional metallic materials, they offer both higher specific material properties, such as strengths, stiffnesses, and an increased energy absorption capacity in case of imp...

In this article, the compression characterization of silicon-based magnetorheological elastomers is addressed, emphasizing the difficulties associated to the test set-up in order to obtain accurate results of the behaviour of the material. Measurement errors associated to friction and vibration coupling due to design flaws in the electromagnet are ...

The concept of near-zero energy conversion from ocean waves is an emerging topic that can be applied to supply power to self-powered applications in sea-crossing bridges. In this paper, a point-absorbing wave energy converter (WEC) with a novel zero-pressure-angle mechanism structure was proposed and investigated. The system includes a wave energy ...

The novel magnetorheological shear thickening polishing fluids (MRSTPFs) were developed by mixing micro cubic boron nitride (CBN) abrasive particles into traditional magnetorheological shear thickening fluids. MRSTPFs were constructed by uniformly fumed silica and polyethylene glycol as shear thickening fluids, carbonyl iron particles (CIPs) as fer...

Ultrasonic waves can transfer power and data to sensors and devices deployed to traditionally inaccessible locations, such as inside the human body or deep in the ocean, eliminating the need for battery replacement. In ultrasonic power and data transfer systems, a piezoelectric transducer converts incident ultrasonic waves to useful electric power ...

Actuator-type applications of high temperature shape memory alloys (HTSMAs) require better understanding of the crack growth behavior at high temperatures as there are few studies on how cracks propagate and cause fracture with phase transformation via cooling and heating under constant load. In this study, hot-extruded and subsequently annealed Ni...

The design and demonstration of a new version of the force measurement system based on the resonance principle by involving shape memory alloy (SMA) is presented. The sensor design enables an electromechanically functional resonator comprising the cantilever beam as the vibratory structural element and the Joule heated SMA as an actuating element. ...

Morphing aircraft are one promising solution to reducing the aviation industry’s environmental impact because they can make aircraft more aerodynamically efficient, thereby reducing greenhouse gas emissions. The design of morphing skins is inherently challenging due to the competing design constraints of needing to be stiff out-of-plane to resist p...
