Orthopedic fixation devices have been employed in the treatment of spinal diseases. Special developed to decrease effect injuries and deformities used neurologic back pain patients. In this study, finite element spine model an adolescent idiopathic scoliotic patient was constructed. The titanium implant system polyetheretherketone (PEEK) were compared regarding their stress distributions. lumba...

Bolt-ball joints are widely adopted in grid structures due to their high installation accuracy and short construction period. Since the bolt is inside joint, it challenging evaluate its health status from outside structure. A finite-element plane-truss structure model, based on actual structure, was constructed investigate influence of rod’s preload overall stiffness bearing capacity Moreover, ...

<p>Lifting <span>petroleum to the surface requires a mechanism called an artificial lift. This is useful for increasing flow of fluids from well. One that uses this method rod pump. The pump system needed appropriate design (through determination value parameters affect) so runs optimally. But changing in real terms not economically and time-efficient. ideal analysis procedure take ...

UNLABELLED The roles of microarchitecture and types of trabeculae in determining elastic modulus of trabecular bone have been studied in microCT images of 29 trabecular bone samples by comparing their Young's moduli calculated by finite element analysis (FEA) with different trabecular type-specific reconstructions. The results suggest that trabecular plates play an essential role in determining...

We present a model for the simulation of the dynamics and fracturing characteristics of wood, specifically its anisotropic behaviour. Existing work focuses on FEM or other uniform lattice representations, with anisotropy being modeled by data driven parameters. Our model instead utilizes an underlying structure that is inherently anisotropic. We utilize an existing description of thin discrete ...

The treatment of patients with tibial fractures and overweight has certain peculiarities due to the increased load on osteosynthesis device. Objective. To compare stress-strain state models lower leg a fracture tibia in upper third diaphysis under influence torsional different options depending patient's weight. Methods. Using finite element method, three types were modeled: using an external f...
