in this paper, simulation and analysis of thin steel cylindrical shells with elliptical cutouts under oblique loading were studied using finite element method. first, the numerical results were validated by the results of experimental test performed by an instron 8802 servo hydraulic machine. also, the effect of cutout angle (θ), cutout size, cutout position (l0/l) and cutout aspect ratios (b/a...

INTRODUCTION Many studies have been performed to evaluate the stress distribution around endodontic posts; those which compared posts composed of different materials are rare. The aim of this study was to compare stresses induced in dentin by three structurally different posts using photoelasticity method. MATERIALS AND METHODS Nine blocks of PSM-5 Photoelastic material with 45×45×10 mm dimen...

This paper proposes mathematical modeling and analysis of ferrofluid lubricated newly designed slider bearing having convex pad (surface or plate) stator with two porous layers attached to the slider. The problem considers the effect of slip velocity proposed by Sparrow et. al.[1] and modified by Shah et. al.[2] at the film-porous interface. The squeeze velocity V=−which appears when the upper ...

In this work, tensile and yield stress and tensile and yield strain of oblique layer functionally graded steels produced by electroslag remelting were investigated. Functionally graded steels containing ferrite, austenite, bainite, and/or martensite layers may be fabricated via diffusion of alloying elements during the remelting stage. Tensile and yield stress and tensile and yield strain of fu...

In this paper the problem on “Magnetic fluid lubrication of porous-pivoted slider bearing with slip velocity by N Ahmad et.al.[7]” has been recapitulated using Jenkin’s model [4] with the additional effect of squeeze velocity of the above plate. It is found that while discussing the above problem, [7] has stated but ignored the term , where +, in their study (Refer equation(2.2)). This paper re...

purpose : to evaluate the results of anterior and nasal transposition (ant) of the inferior oblique muscle (io) in patients with the io muscle overaction methods : this retrospective case series included patients with io muscles overaction, in whom ant of the io muscle was performed. in patient with simultaneous horizontal deviation, horizontal strabismus surgery was also performed. they were e...

Near side impact crashes – especially pole impacts – have the potential to induce antero-lateral oblique loads to the chest. Current side impact dummies and most laboratory experimental studies have been designed to assess direct lateral impacts. A recent analysis of real world crashes indicated that the human chest experiences oblique loading in side impact crashes – in particular crashes into...
