A comparative study on the stress distribution around dental implants in three arch form models for replacing six implants using finite element analysis.

Background: Dental implant is a method to replacement of missing teeth. It is important for replacing the missed anterior teeth. method is a safe method for evaluation of stress distribution.

Analytical Study of a Pin-Loaded Hole in Unidirectional Laminated Composites With Triangular and Circular Fibers.

The problem of stress concentrations in the vicinity of pin-loaded holes is of particular importance in the design of multilayered composite structures made of triangular or circular glass fibers. It is assumed that all of the fibers in the laminate lie in one direction while loaded by a force p at infinity, parallel to the direction of the fibers. According to the shear lag model, equilibrium equations are derived for both types of fibers.
