Cartilaginous tissues, such as articular cartilage and the annulus fibrosus, exhibit orthotropic behavior with highly asymmetric tensile-compressive responses. Due to this complex behavior, it is difficult to develop accurate stress constitutive equations that are valid for finite deformations. Therefore, we have developed a bimodular theory for finite deformations of elastic materials that all...
ESO 566-24 is an extraordinary barred galaxy, which has four regularly spaced spiral arms in blue light images. This type of four-armed spiral structure, which is rare among the spiral population, is clearly seen also in near-infrared images, and thus is present in the old stellar population. We have constructed dynamical models of ESO 566-24 in order to understand the cause of its four-armed s...
The aim of this study was to assess the stress patterns on the peri-implant zone and residual alveolar ridge in different overdenture attachment system designs by the photoelasticity method. Four attachments systems were tested: O-ring, ERA, Bar-clip, and Bar-clip/O-ring association. The prostheses were loaded with 100 N in five pre-determined points and the photoelastic model was evaluated by ...
Rotation curves and velocity dispersion profiles are presented for both the stellar and gaseous components along five different position angles (P.A.=5, 50, 95, 125, and 155) of the nearby barred spiral NGC 6221. The observed kinematics extends out to about 80 from the nucleus. Narrow and broad-band imaging is also presented. The radial profiles of the fluxes ratio [N II] (λ 6583.4 Å)/Hα reveal...
The use of photoelastic analysis contributes to the rehabilitation of patients with oral-sinus-nasal sequelae, which in turn affect important functions such as chewing, swallowing, and speech. The prosthetic rehabilitation with implant-retained dentures is a suitable treatment option. The purpose of this study was to verify, by using a photoelastic analysis, the stress distribution in implant-r...
Wood is a non-homogeneous and orthotropic natural polymer material. It important to test the wood shear modulus elastic constants accurately reliably using dynamic methods. Based on introduction of advantages six common methods for testing modulus, such as free plate torsional mode method, bar vibration Timoshenko beam iterative issues associated with applicability accuracy these are also point...
