In this work, we attempt to simulate residual stresses and springback of a deformed metal pan based on a micro-macro modelling of the elastic and plastic strains. Samples cut out of an aluminium plate, under different angles relative to the rolling directi ...
Undertaken in the field of design methods for flexible pavement, the present study focuses on the introduction of traffic loads, applied mainly to mechanistic empirical methods. In such research, strains due to traffic loads — calculated by pavement modeli ...
In this paper, the behaviour of fibre Bragg grating sensors subjected to transversal as well as axial strains is characterized, both in the case of low-birefringent and polarization-maintaining single-mode optical fibres. Two configurations are considered. ...
We review the nature of glass transitions and the glasses arising from a square-well potential with a narrow and deep well. Our discussion is based on the mode coupling theory (MCT), and the predictions of glasses that we make refer to the “ideal� glas ...
This work connects of three domains of fiber optics : the fiber Bragg gratings (FBG), the optical low coherence reflectometry (OLCR) and the fiber optical sensors (using FBGs, the OLCR or a combination of both). Fiber Bragg gratings are fiber optic devices ...
With progressing age, large arteries diminish their longitudinal stretch, which in extreme cases results in tortuosity. Increased age is also associated with loss of vessel distensibility. We measured pressure-diameter curves from muscular porcine carotid ...
Semiconductor–metal hybrid structures can exhibit a very large geometrical magnetoresistanceeffect, the so-called extraordinary magnetoresistance (EMR) effect. Using the finite element method, we study the EMR effect in rectangular semiconductor–metal hybr ...
Recently, it was shown that semiconductor-metal hybrid structures can exhibit a very large magnetoresistance effect, the so-called extraordinary magnetoresistance (EMR) effect. This led to the perspective of using EMR devices in magnetic-field sensors and ...
We report on a Raman study of strained wurtzite GaN quantum dots embedded in AlN spacers. Various laser excitations between 2.33 and 3.81 eV were used, which allows for selective probing of the dots, through resonant enhancement of the Raman signal. A dire ...
By means of a Gleeble machine, the flow stress at steady-state creep in an AA3103 aluminium alloy has been measured for temperatures and strain rates relevant for thermally induced deformations in DC casting. The strain rate has been determined by measurin ...
