In order to evaluate the reliability of cracked cylindrical shell effectively and reasonably, study load capacity structures understand failure modes structures, in this paper finite element method is adopted for shells with mixed mode crack. The models an inclined through crack under external pressure were established by method, elastic elastic-plastic buckling loads calculated. influences len...

Recently, a large amount of studies have been related to nonlinear systems with multi-degrees of freedom as well as continuous systems. The purpose of this paper is to optimize passive vibration absorbers in linear and nonlinear states for an Euler-Bernoulli beam with a nonlinear vibratory behavior under concentrated moving load. The goal parameter in the optimization is maximum deflection of t...

The purpose of this study was to elucidate the relation between distribution of occlusal contacts in unilateral shortened arch and prosthodontic treatment, those occlusal loads, coordinates of the points and amounts, in relation to masticatory musculature activities by EMG and Prescale. Occlusal contacts and loads were measured by extra-thin-layer of pressure indicator (Prescale Fuji Film Co.),...

This paper presents an experimental study on the pullout behaviour of inclined shallow plate anchors subjected to axial pull in sand. The 1g model tests were performed examine effects anchor inclination and sand–anchor interface conditions load–displacement response associated failure deformation mechanisms at various embedment ratios sand densities. capacity was found increase continuously wit...

The spatial distribution of desorbing O(2) and CO(2) was examined in 193-nm photoinduced reactions in O(2)+CO adlayers on stepped Pt (112)=[(s)3(111)x(001)]. The O(2) desorption collimated in inclined ways in the plane along the surface trough, confirming the hot-atom collision mechanism. In the presence of CO(a), the product CO(2) desorption also collimated in an inclined way, whereas the incl...

[Purpose] This study investigated the effects of inclined treadmill walking on pelvic anterior tilt angle, hamstring muscle length, and back muscle endurance of seated workers with flat-back syndrome. [Subjects] Eight seated workers with flat-back syndrome who complained of low-back pain in the L3-5 region participated in this study. [Methods] The subjects performed a walking exercise on a 30° ...

Retrospective studies have suggested that dancers performing on inclined ("raked") stages have increased injury risk. One study suggests that biomechanical differences exist between flat and inclined surfaces during bilateral landings; however, no studies have examined whether such differences exist during unilateral landings. In addition, little is known regarding potential gender differences ...

This paper is aimed to examine the dynamics of cracked thin rectangular plates subjected a moving non-stationary random load. A load considered with constant mean value, velocity along plate, and five different covariance patterns,the white noise, constant, exponential, cosine wave, exponential covariance. Accordingly, an intact plate’s orthogonal polynomials in combination well-known corner fu...

An extensive program of laboratory testing was conducted on ring footing rested gypseous soil brought from the north Iraq (Salah El-Deen governorate) with a gypsum content 59%. There are limited researches available, and even fewer have been done experimentally to understand how footings behave; almost all previous works only concern behavior under vertical loads, Moreover, relatively few studi...
