Finite Element Analysis of Contact Stress for Particle Reinforced Composites

Abstract:

Article Preview

General structures or machines are firmly connected by bolts so that they have many contact surfaces. Between these contact surfaces, there is a movement that vibrates with tiny amplitude, which causes friction, leading to fretting damage. This damage causes a remarkable reduction in the fatigue strength of the structures sub-materials, leading to remarkable fall-down of life span of machines and structures. The particle reinforced composites under research in the aerospace and automobile industries, theoretical analysis and research on fretting fatigue involved with contact are needed, but there are few domestic studies. Therefore, this study is to identify cracking damage, its initiation, growth direction and location by considering the strength load and contact (surface/surface) in particle reinforced composites. So it performed a study on ellipsoidal particle reinforced composites that have contact force under tensile load. This study performed a theoretical analysis and a fretting test to identify damage mechanism to industrial structures as well as aerospace and automobile industries according to expanded coverage of application and development of the composites.
