STATEMENT OF PROBLEM Mechanical properties of denture acrylic resins are important for the clinical success of multiple types of prostheses. Acrylic resins must be strong and resilient so as to withstand impact. Few studies utilize cyclic loads to characterize material response to repeated stress. PURPOSE The purpose of this study was to evaluate static and dynamic flexure properties of a var...

In this paper, we demonstrate that a Flexure-FET [1] (flexure sensitive field effect transistor) can dramatically enhance the sensitivity of stress based chem-bio sensors. A Flexure-FET translates any change in the stress of the suspended gate into corresponding change in the drain current of the integrated transistor, thereby offering direct electrical readout of the sensor signal. Moreover, w...

I t has been demonstrated that strychninization in Asterias is followed by extreme dorsal flexure of the rays and consequent inability to make righting movements ~ (Figs. 1, 2, and 3). This "spasm" position of the rays is accelerated and accentuated by sensory stimulation. In order to determine the location of the muscles which cause this action, the dorsal, myodermal sheath is cut from all fiv...

Modifications of the molluscan feeding apparatus have long been recognized as a crucial feature in molluscan diversification, related to the important process of gathering energy from the environment. An ecologically and evolutionarily significant dichotomy in molluscan feeding kinematics is whether radular teeth flex laterally (flexoglossate) or do not (stereoglossate). In this study, we use a...

A Local Load Sharing (LLS) model recently developed by Curtin and co-workers for the numerical simulation of tensile stress-strain behavior in fiber-reinforced composites is used to predict the tensile strength of metal matrix composites consisting of a Titanium matrix and unidirectionally aligned SiC fibers. This model is extended to include the effects of free boundary conditions and non-cons...

a 5th order shear deformation theory considering transverse shear deformation effect as well as transverse normal strain deformation effect is presented for static flexure   analysis of simply supported isotropic plate. the assumed displacement field accounts for non-linear variation of in-plane displacements as well as transverse displacement through the plate thickness. the condition of zero ...

this study was carried out in the winter of the year 2007 in a dairy herd at the vicinity of tehran (eslamshahr). measurements were performed on 18 holstein cows during first-lactation. five holstein dairy cattle were randomly selected and clinically studied, too. length of the claw’s dorsal flexure was measured with a ruler and also the hooves trimmed in the toe vertically for measuring of the...
