This paper analyzes the effects of structures and loads on the static bending and free vibration problems of bilayer beams. Based on static mechanical equilibrium and energy equilibrium, the static and dynamic governing equations of bilayer beam are established. It is found that the value of the thickness ratio has a significant effect on the static and dynamic responses of the beam, and the st...

Static forces have been used for more than a century to modulate osteogenesis of craniofacial sutures in not only laboratory research, but also clinical practice. Whether cyclic forces more effectively stimulate sutural osteogenesis than static forces is unknown. Here, the premaxillomaxillary sutures of growing rabbits received in vivo exogenous static forces with peak magnitude of 2 Newtons, o...

Magnesium alloys are attracting great interest from the automotive industry because of the potential for weight reduction. An AZ91D cast alloy was studied in the current work to understand the effect of heat treatment on the microstructure and dynamic compressive properties. The selected heat treatments include solution treatment (T4) and solution treatment followed by aging (T6). The as-cast a...

Structural health monitoring (SHM) is an effective way to maintain the civil infrastructure against unexpected collapse. In recent years, many researchers have developed numerous damage detection methods to identify possible damage locations. The damage locating vector (DLV) method proposed by Bernal has received significant attention because this method was verified by a series of proof-of-con...

Sutures are fibrous connective tissue articulations between intramembranous craniofacial bones. Sutures are composed of fibroblastic cells with their matrices in the center and osteogenic cells in the periphery producing a matrix that is mineralized during skeletal growth. Whether oscillatory forces stimulate sutural growth is unknown. In the present work, we applied static and cyclic forces wi...

The present study deals with the quasi-static and high strain rate characterization of Kevlar-129 based thermoplastic composites. Two different matrices, namely, Polypropylene (PP) Polyetherimide (PEI) were used to manufacture composite laminates. Quasi-static compression tests performed at rates 0.041 s ?1 0.045 . High using a split Hopkinson pressure bar apparatus within ranging from 2548 437...

Florida Department of Transportation (FDOT) sponsored research performed at the University of Florida resulted in developing a wireless monitoring and real time static capacity estimate technology for driven piles. This new technology, Embedded Data Collector (EDC), uses two levels of instrumentation, embedded in the body of precast prestressed concrete piles near the head and tip. Strain and a...
