By means of geometric modeling for the complicated shape of violin sounding box and Finite Element Analysis, the structural parameters of violin box, including thickness of violin plate, height and distribution and change of the shape of arch in front plate geometry, status of bass bar and sound-post etc, are investigated for their influence on vibration patterns and frequency response of violin box. Experiment is carried out for measuring the frequencies responses of violin box to verify the results of the Finite Element Analysis.

The Impact

The marine riser bears various power loads during operation. We designed the Quadrupole-type magnetic measurement probe based on the inverse magnetostrictive effect (the impact of stress on the magnetization) and performed finite element simulation and experimental analysis. The results of both the finite element analysis and magnetic measurement basically follow the same trend, so we conclude that this four-pole magnetic probe measurement can quantitatively evaluate the force state in a marine riser.

The Finite Element Analysis

According to the behavior of shape memory alloys, a structure of removable shape memory alloy pipe joint was designed. The contact manner of two parts of this structure is cone-globe. Cone-globe sealing is the key point of this structure’s sealing. Therefore the finite element analysis software ANSYS was used to simulate and calculate the sealing. The result shows that the width of the sealing surface and the contact stress altered with the change of structural parameters, which affected the sealing most. According to the value of the sealing surface’s width and the contact stress, the structural parameters including cone angle can be definitely settled.

The Finite Element Analysis

The tubular textile composite material as the liner is inversed in the pipeline by gas or water pressure, and then the damaged pipeline can be rehabilitated. During inversion, because of the inversion pressure, the tubular textile composite material must endure the complicated stress and strain. Adopting the Finite Element Analysis, the paper analyzed the stress and strain of the tubular textile composite during inversion, and the finite element simulation data compared with test data. The results show that the stress and strain in head of the tubular textile composite material during inversion is instability, where the stress is concentrative, so the head of the tubular textile composite material is easy to break.

The Finite Element Analysis

The aim of the finite element analysis (FEA) is to determine the stress and deformation state of all elements of four mechanical assemblies under certain loading and fastening conditions of the structure. The structure of the finite element analysis consists of GIC and 4 geometric variables (no bone loss, 1 surface radial loss, 2 surfaces and circumferential loss). Geometric reconstruction of simulated elements is done based on the X-ray scan images. The DICOM image collection is imported into Mimics 10.01, where two color layers are applied, which are then transformed into volumes. Surface integrity was accomplished using Geomagic Studio 2013 software. Subsequent to the reconstruction, classical geometric modeling was carried out using the SolidWorks 2013 CAD environment. Four geometric models were made and the assembly described above was inserted. Finite element analysis was performed with the Ansys 13 software. For resin composite restorations, in the case of circumferentilly bone loss, the restoration pressure drops due to increased tooth elastic deformation possibilities. In case of bone loss on one face and two sides of the tooth, there is a strong pressure on the cementum-bone interface, due to the bending effect that occurs. Pressures in dental root restorations are higher in the case of reconstruction using resin composite.

Abstract The effects of variations in stiffness and geometry on the nonuniformity of tires are investigated by using the finite element analysis. In order to evaluate tire uniformity, a three-dimensional finite element model of the tire with imperfections is developed. This paper considers how imperfections, such as variations in stiffness or geometry and run-out, contribute to detrimental effects on tire nonuniformity. It is found that the radial force variation of a tire with imperfections depends strongly on the geometrical variations of the tire.
