OBJECTIVE This study aimed to evaluate the bending moments, and compressive and tensile forces in implant-supported prostheses with three, four or five abutments. MATERIAL AND METHODS Ten Pd-Ag frameworks were tested over two master models with: 1) parallel vertical implants, and 2) tilted distal implants. Strain gauges were fixed on the abutments of each master model to measure the deformati...

The relative strength of posterior plating and dual medial-lateral plating for comminuted olecranon fractures has not been evaluated. Fifteen male cadaveric elbows with simulated highly comminuted olecranon fractures were tested to failure via cantilever bending. The strength of dual medial-lateral plates and a single posterior plate with and without an intramedullary screw was evaluated. The m...

Controllable bending stiffness and damping has significant applications in soft robotics, especially for soft slender manipulator arms inspired by octopus tentacles. The bending moment on a solid slender beam is balanced by the sum of moments generated by internal stresses. Resulting stresses are not controllable and decided by the bending curvature, area moment of inertia and elastic modulus o...

This paper discusses the long-term behavior of a series of highly-loaded, spun concrete pole specimens prestressed with carbon fiber-reinforced polymer (CFRP) tendons, which were subjected to outdoor four-point bending creep tests since 1996 in the frame of collaboration with the Swiss precast concrete producer, SACAC (Società Anonima Cementi Armati Centrifugati). The 2 m span cylindrical beams...

the structural slenderness ration (height/ with) is one of the title that can be discussed in quake design of building. but unfortunately, in  iranian code isn’t mention this mater.in this article, bending and bracying structures system are chosen with slenderness ratio 2 upto 6. (11, 17, 23, 29, 35 stage).all of structure are analysed and designed in linear method, then analysed in unlinear me...

1. Abstract This paper is aimed at minimizing the bending moment which caused in curved surface structures. The dimension of structure weight is three, and the material strength dimension is two. Therefore, the bigger the structure scale is, the more bearing capacity will be occupied by initial stress caused by dead load. Thus, with the growing of span, structural form will be greatly restricte...

A one-dimensional local bend model is used to describe the variation of electronic properties of acetylene in vibrational levels that embody large amplitude local motions on the S0 potential energy surface. Calculations performed at the CCSD(T) and MR-AQCC levels of theory predict an approximately linear dependence of the dipole moment on the number of quanta in either the local bending or loca...

Strength of both muscles and bone are important for fracture prevention in osteoporotic individuals. Therefore, drugs that are preclinically tested in animals for preventing or treating osteoporosis, and reducing fracture risk, should not only be checked for their effects on bone strength, but also for those on muscle strength. We developed a rat model to measure both in the same animal, using ...

Temnospondyl amphibians were important members of the tetrapod fauna and the terrestrial vertebrate food chain during the Paleozoic and early Mesozoic. The “labyrinthodont” teeth of these amphibians are not simple cones; they exhibit an overall tooth form that is relatively complex and generally conserved over large temporal and phylogenetic ranges. We assess the functional morphology of these ...

The bending strength of a wide variety of bony types is shown to be nearly linearly proportional to Young's modulus of elasticity/100. A somewhat closer and more satisfactory fit is obtained if account is taken of the variation of yield strain with Young's modulus. This finding strongly suggests that bending strength is determined by the yield strain. The yield stress in tension, which might be...
