Abstract:
Nowadays, the use of finite element Software applications in enigineering departments has become Inevitable and commonplace. Acceptance of the necessity of using such software applications for reducing the cost of research and development does not require any evidences of financial instruments to be presented. Reducing design and manufacture time together with pseudo-empirical approach has cuased the finite element science to become a conventional designing tools.
Since contact is the main method to apply a load on a ductile object,and stress concentration caused thereby is often a major cause of failure in mechanical parts, the issue of contact is a fundamental topic in mechanics of solids. Standard finite element method is one of the most powerful numerical analysis methods in this arena; and despite of its widespread usage in modeling and in solving such problems, it faces with serious limitations and difficulties.
In this study using normal elements and computing acceptable results with them are considered to be main rules , so the methods used in these thesis can be used easily in other situations, and is no need to use not-conventional and move complex methods
