Analysis of Linear Expansivity of Metallic Strips Joined Linearly and with Circular Joints
M. Jiya, K. Udeoji

Abstract
In this paper the linear expansivity of a metallic strip that are joined linearly and with circular joints were analyzed. The Linear expansivity equations were converted into Integro-differential equation (IDE) and the resulting equation are then solved using Variational Iteration Method (VIM). The results obtained were also analysed for various parameters (temperature, length and time) at a specific rate of change in temperature. It was observed that both the temperature and length of the metallic strip are directly proportional to time.
