In this paper, the response of hybrid composite laminate plate reinforced by the smart wires (shape memory or the SMA wires) subjected to low velocity impact is studied. The smart wires are embedded within the layers of the composite laminate. The effect of the smart wires on contact force history, and deflection of these structures is investigated. The first-order shear deformation theory as w...

The smart cable with embedded distributed fiber optical Bragg grating (FBG) sensors was chosen as the object to study a new diagnosis method about broken wires of bridge cable. The diagnosis strategy based on cable force and stress distribution state of steel wires was put forward. By establishing bridge cable and cable steel wires model, the broken wires sample database was simulated numerical...

AIM To demonstrate the feasibility of the wearable smart glasses, PicoLinker, in guide wire insertion under fluoroscopic guidance. METHODS Under a fluoroscope, a surgeon inserted 3 mm guide wires into plastic femurs from the lateral cortex to the femoral head center while the surgeon did or did not wear PicoLinker, which are wearable smart glasses where the fluoroscopic video was displayed (1...

There are two different ways of using SMA wires as actuators for shape control of flexible structures; which can be either embedded within the composite laminate or externally attached to the structure. Since the actuator can be placed at different offset distances from the beam, external actuators produce more bending moment and, consequently, considerable shape changes with the same magnitude...

The progress in the design and development of small-scale computing devices to this date has established the possibility to integrate these computing devices into virtually all everyday objects. For the near future we expect the availability of even smaller and more densely integrated devices providing us with even more resources and computing power. Existing applications will benefit from this...

Unlike conventional steel strands, the smart strand supports strain-measuring function and adopts different materials for its core wire and helical wires. This study intends to analytically derive the nonlinear stress-strain model of this strand made of two materials. The effect of the bending moment and torsional moment of the helical wires on the overall load within the range of geometric sha...

Flexible AC Transmission System (FACTS) controller has got unanimous acceptance in the electric power industry due to their control capability especially transmission and sub networks. These FACTS devices play a decisive role stability enhancement effective asset utilization. The controllers suffer from grave drawbacks such as colossal size, poor reliability, high cost, unavailability of experi...

Smart film crack monitoring method, which can be used for detecting initiation, length, width, shape, location, and propagation of cracks on real bridges, is proposed. Firstly, the fabrication of the smart film is developed. Then the feasibility of the method is analyzed and verified by the mechanical sensing character of the smart film under the two conditions of normal strain and crack initia...
