Numerous techniques to determine stress distribution around the peri-implant bone, for instance photoelastic model, strain gauge analysis, and three-dimensional (3D) finite element analysis have been extensively studied, however finite element analysis still remains the most widely utilized technique. This paper briefly reviews the fundamental concepts, applications pertaining to dental implants, various advantages as well as limitations of finite element analysis. The finite element method not only serves as a significant tool for biomechanical analysis, it also enables to reveal stress within complex structures and analyzing their mechanical properties. Keeping in mind the various limitations of the method further improvements might be made which would help to widen its range of applications in various domains of dental sciences.

Elastic Multibody System

In classical mechanics, determining the governing equations of motion using finite element analysis (FEA) of an elastic multibody system (MBS) leads to a system of second order differential equations. To integrate this, it must be transformed into a system of first-order equations. However, this can also be achieved directly and naturally if Hamilton’s equations are used. The paper presents this useful alternative formalism used in conjunction with the finite element method for MBSs. The motion equations in the very general case of a three-dimensional motion of an elastic solid are obtained. To illustrate the method, two examples are presented. A comparison between the integration times in the two cases presents another possible advantage of applying this method.

At present, the finite element method is used to calculate the strength and deformation of the steel transmission pole less. Using ANSYS to model steel transmission pole, loading, analysis, the results show that, the traditional method of strength calculation and finite element analysis results are very close, the traditional method of deformation calculation and finite element analysis results has a certain bias. As long as the establishment of three-dimensional model of the steel transmission pole, the applied load and boundary conditions to meet the actual, finite element analysis can provide a more reliable basis for the design and verification of the steel transmission pole.

This paper presents the use of Three-Dimensional Finite Element Method (3D-FEM) for biomechanical analysis on dental implant prosthetics. This research focuses on three patents of threads of dental implant systems from United States Patent and Trademark Office (USPTO) and two new conceptual design models. The three-dimensional finite element analysis is performed on dental implant models, with compressive forces of 50, 100, and 150 N, and a shear force of 20 N with the force angle of 60 degrees with the normal line respectively. The Stress and displacement analysis is conducted at four different areas (abutment, implant, cortical bone, and cancellous bone). Findings from this research provide guidelines for new product design of dental implant prosthetics with stress distribution and displacement characteristics.

Abstract Objective To evaluate the biomechanical analysis and effect of the wrist protector and provide a theoretical basis for wrist fractures and the optimal design of wrist protectors. Methods 6 cadaveric wrist models were axially loaded 600 N stress, and the stress magnitude and distribution of the experimental group (wearing wrist protectors) and control group were obtained. Furthermore, a three-dimensional finite element analysis was conducted to verify the scientificity and effectiveness of the models. Results The stresses on the radial distal palmar, ulnar distal palmar, radial distal dorsal, ulnar distal dorsal, radial proximal palmar and ulnar proximal palmar units in the experimental group were lower than those in the control group (P < 0.05). However, the stresses on the radial proximal dorsal and ulnar proximal dorsal units were higher than those in the control group (P>0.05). Conclusion The stress on the radioulnar palmar unit was high, while the radioulnar dorsal unit one was relatively low. Within the range of physiological loads, wearing wrist protectors can significantly reduce the stress on the radioulnar distal palmar, radioulnar proximal palmar and radioulnar distal dorsal units.

Cervical Spondylotic Radiculopathy

Cervical spondylotic radiculopathy (CSR) is the most commonly encountered cervical spine disorder. Cervical manipulation has been demonstrated as an effective therapy for patients. However, the mechanisms of manipulations have not been elucidated. A total of 120 cervical spondylotic radiculopathy patients were divided into the “three-dimensional balanced manipulation” treatment group (TBM group) and control group randomly. The control group was treated with traditional massage; the TBM treatment group was treated with “three-dimensional balanced manipulation” based on traditional massage. The symptoms and clinical efficacy of the patients were compared before and after treatment for one month. A three-dimensional finite element model was established. The mechanical parameters were imported to simulate TBM, and finite element analysis was performed. The results showed that the total effective rate was significantly higher in the TBM group compared with the control group. The biomechanical analysis showed the vertebral body stress was mainly distributed in the C3/4 spinous processes; the deformation mainly concentrated in the anterior processes of the C3 vertebral body. The intervertebral disc stress in the C3~C7 segment was mainly distributed in the anterior part of the C3/4 intervertebral disc, and the deformation extends to the posterior part of the C3/4 nucleus pulposus. In summary, these data are suggesting that TBM was effective in CSR treatment. The results of the finite element model and biomechanical analysis provide an important foundation for effectively avoiding iatrogenic injuries and improving the effect of TBM in the treatment of CSR patients.

Today in the world, shipyards industry work continuously and build a ship in limited time. They need a lot of cranes in different tonnages to lift and move the parts of the ships. Projects of the cranes design in need of the shipyards. While designing the crane geometry, the load which will be lifted, the lifting height and the situation of the area where the crane will work should be considered. The main characteristics as the height of the crane, the distance between the rails, the lifting height, speed of the crane and speed of the trolley are determined. The geometry of all parts and the features of the power and transmission components are specified. The suitability of the geometry is tested with an analyze program. Three dimensional geometry of the crane is built with a CAD program, and then this geometry is modeled with using the finite element method.
