The support system for a proximal fracture of the femur is studied by means of the finite element method. The support system of the Gamma III by Stryker is used for this study due to the versatility and simplicity of the system. The variance of each system was modeled to validate the results. Parametric studies between the models were conducted and design improvements were then tested against the existing parameters. Given the material properties for the Ti-6 AL-4V support system and bone, the...

Finite element models can be used to discern the location and severity of damage in structures. This is frequently pursued by using the differences in measured and computed natural frequencies, in conjunction with the sensitivities calculated using the FE model. Given that a modal test produced a limited number of natural frequencies for a structure, the concept of Artificial Boundary Conditions (ABC) was developed, which yields additional natural frequency information for a structure. This is...

The objective of this study is to investigate joint strength of the scarf joint configuration, constructed from carbon and glass woven fabric hybrid laminates, with different material combinations. Glass/glass, glass/carbon, carbon/glass, and carbon/carbon are tested under various loading conditions like tension, compression, bending and shear loading. Both experimental and computational studies are conducted. For the experimental study, specimens made of scarf joints using carbon and glass...

This investigation is concerned with minimum weight designs of arch structures. Using the finite element method, the arch is modeled by contiguous bar-beam elements. Element stiffness coefficients in terms of local degrees of freedom are related to system degrees of freedom through local to global coordinate transformations. After coordinate transformations, element stiffness coefficients are assembled into FEM stiffness equations for the arch structure. An objective function for weight...

In recent years, several computational models were published for the analysis of pipelines subjected to ice scour. With one exception, most of these models assumed uniform seabed soil properties. This paper studies the effects of different seabed soil stratigraphies on the ice scour process. Influence of various stiffer and softer soil sequences on the pipeline stresses are analyzed. Effects of reworking or remolding of soils by recurrent scours are studied. The question of existence of...

This paper presents the results of modernization of gear micropump casing in order to achieve minimization of overall dimensions and mass of the construction. Three different cases of the pump casing size were analyzed during numerical simulations with the use of finite element method (FEM). The dimensions of the first of the casings were identical to prototype unit, the second model was characterized by 15% reduction in size and the third casing was reduced by 25%. During the analysis, stress...

In structural dynamics the ability of a finite element model, or (FEM), to accurately represent a structure's dynamic response (natural frequencies and mode shapes) determines its utility as a solution tool. Oftern the model needs to be updated or improved to better represent the structure it is modeling. An updated or improved model of an undamaged structure is often needed in order to identify damage in an in-service structure. A difficulty generally arises in trying to slove for this error...

In this paper, the breast cyst diagnosis based on the surface temperature profile is proposed. The temperature profiles of normal breasts and breasts with cyst have been investigated. Heat transfer inside the breast is modeled by the Penne’s bio-heat equationand solved by the finite element method using COMSOL Multiphysics software. A two dimensional (2-D) cross-section of the breast is modeled by a semicircle, whereas the cyst is modeled by a small circle. The temperature distribution on...

The objective of this study was to develop an analytical model of the basic hierarchical structure of the human bone. The model computed the stiffness of composite collagen fibers comprised of collagen fibrils and hydroxyapatite mineral crystals. Next, the stiffness of the concentric lamella was computed utilizing the stiffness of the collagen fibers and layer information. Finally, the effective stiffness of the bone was estimated. In order to determine the stiffness of the collagen fiber, a...

The objective of this research was to analyze the effects of impact loading on electronic component failure. A standard fiberglass composite printed circuit board (PCB) card was used in two impact tests. The first test consisted of a PCB card with four adhered strain gauges, which were mounted inside an aluminum box fabricated for testing. Impact testing was conducted with weights ranging from 0 to 30 lb., and the corresponding strain values were recorded. For the second set of impact tests, a...

The Finite Element method is one of the most widely used methods by Engineers in the various areas of activity, especially Mechanical Engineering, to design or solve problems. However, the understanding of the method is not always easy to perform, since in the literature, when explaining the method, the examples are generic or presented quickly. Thus, this paper presents the solution of a problem involving a rocking beam (set), which is solved analytically and later by the finite element...

Benthic shells can contribute greatly to the scattering variability of the ocean bottom, particularly at low grazing angles. Among the effects of shell aggregates are increased scattering strength and potential subcritical angle penetration of the seafloor. Sand dollars (Dendraster excentricus) occur commonly in the ocean and have been shown to be significant scatters of sound. In order to understand more fully the scattering mechanisms of these organisms, the scattering from individual sand...

In 1979, Boresi and Salinas prepared a report that formulates the problem and proposes a solution procedure. The report was the result of an interest in the transient behavior of a gun barrel during recoil following firing. This research considers a cantilever beam which can move axially in and out of a rigid frictionless hole and is free to vibrate laterally outside the hole. Two Euler equations describing the lateral and axial motion of the beam are presented. A transformation of coordinates...

The use of cargo handling equipment in the industry in general is extremely important for logistics, since their contribution in receipt of material, until the production stages. Since they are subjected to severe mechanical stress, it is necessary for them to resist to these loading. This work aims to verify the structural integrity of a single girder crane designed by “ARPI Engenharia”, according to standard NBR 8400. In order to evaluate the crane structure and compare the mechanical...

A connecting rod works in variably complicated conditions, and is subjected to not only the pressure due to the connecting rod mechanism, but also due to the inertia forces. Its behavior is affected by the fatigue phenomenon due to the reversible cyclic loadings. When the repetitive stresses are developed in the connecting rod it leads to fatigue phenomenon which can cause dangerous ruptures and damage. Yield, fatigue and buckling characteristics are often used as evaluation indexes for the...

The geometry for the NASA Scanning Radar Altimeter (SRA) is shown. It transmits a 8-ns duration pulse at Ka-band (8.3 mm) and measures time of flight as it scans a 1 degree (two-way) beam from left to right across the aircraft ground track. The most recent configuration determines the surface elevation at 64 points spaced at uniform angular intervals of about 0.7 across a swath whose width is about 0.8 times the aircraft altitude. The system generates these raster lines of the surface...
