Abstract. A comprehensive 3D visco-elasto-plasto-damage constitutive model of concrete is proposed to analyze its behaviour under long-term and cyclic loadings. This combines the visco-elasticy plasticity theories together with damage mechanics. The work aims at providing an efficient capable predicting material behaviour, taking into account time-dependent effects mesoscale. visco-elastic part...

METHODS: Design: Retrospective interventional case series. Study population: 21 eyes from 21 patients who underwent visco-bubble technique for DALK, which involves the injection of ophthalmic viscosurgical devices (OVDs) into the deep stroma to form a visco-bubble to separate Descemet ́s membrane from the posterior stroma. Surgeries were performed between May 2010 and January 2013. Main outcome ...

In this study, we investigated the effect of different solutions--coffee, tea, Turkish coffee, artificial saliva, mouthwash, denture cleanser, and distilled water--on the bond strength of soft lining materials (one acrylic- and three silicone-based) to acrylic resin. Acrylic specimens (40x10x10 mm) were prepared for the bond strength test. The specimens were stored in different solutions and te...

In the present study, the effects of the acute and chronic oral administrations (po) of curcumin in the absence and presence of morphine and naloxone was investigated on the sensation of acute corneal pain in rats. Acute corneal pain was induced by the local application of hypertonic saline (5 M NaCl) on the corneal surface, and the number of eye wipes was then counted for 30 s. Subcutaneous (s...

Four hundred and forty-six general, vascular and gynaecological surgical patients were recruited to a two centre, double triangular sequential randomised controlled trial to compare the post-operative pressure sore incidence in patients positioned on the standard operating table mattress with those positioned on the dry visco-elastic polymer pad (Action Products Inc.). Two hundred and twenty tw...

A two dimensional numerical study has been performed to investigate on heat transfer of hydrate slurry transported by a visco-elastic fluid in a cavity. In order to investigate the optimum geometric parameter, the effects of the rib height and the cavity length were changed in three steps, respectively. From the results, it is found that hydrate particles dispersed with Newtonian fluid (water) ...

Various models of tumor growth are available in the litterature. A first class describes the evolution of the cell number density when considered as a continuous visco-elastic material with growth. A second class, describes the tumor as a set and rules for the free boundary are given related to the classical Hele-Shaw model of fluid dynamics. Following the lines of previous papers where the mat...

MOC (method of cell) is a new method of investigating wave propagating in material with periodic microstructure, and can reflect the effect of microstructure. Wave propagation in periodically laminated medium consisting of linearly elastic layers can be treated as a special application of this method. In this paper, it was used to simulate the dynamic response of carbon-phenolic to impulsive lo...
