Finite Element Analysis of Fastener Joints in Metallic and Orthotropic Structures

Abstract

Joints are essential to connect different components of a structure or sub-assemblies and they are inevitable in any large scale engineering structure. Among various methods of joining, fastener (pin) joints are common in cases where periodic assembly and dis-assembly are required. To understand the mechanism of load transfer in these joints, extensive studies have been made in the past. In the present work, NISA code for finite element analysis is made use to understand the mechanics of load transfer in such joints. The basic configuration considered is actually a pin in a plate for both metallic as well as orthotropic plates. Both the pin loading and plate loading cases have been studied. The effect of load parameter, stresses and type of fit namely push, clearance or interference on contact/separation angle have been studied and presented. The results obtained could be of immediate value to practical problems.
