Project Title: Analysis of Chain Link

By: Anuj Salke (UIN 660484908) Sujay Khamitkar (UIN 662253535)

Problem Statement: To study the stresses that occurs in a chain link when it is subjected to loads and to verify the results analytically. The aim of the project is to calculate the stresses induced in a chain link analytically and verify if these results are same with the results obtained from ANSYS. We found that they are not exactly same but somewhat similar.
Background information: Chain link has been estimated to be in use since 220 BC1. A chain is made of multiple elements as shown in the figure. Fig. A. (Chain Link) …show more content…
Various materials used for manufacturing a chain link are steel, stainless steel, carbon steel, alloys etc.
The chain link which we have considered is used for hoisting purposes, this is because the oval shape is ideal for crane hook as the depth of the crane hook is greater than the width. We will study stresses induced in the link. It is necessary to study the stress distribution, deformation and deflection so as to avoid design failure and loss. The necessary information required for the project like material properties, type of load to be applied, intensity of load is taken from the textbook ‘Strength of Materials ’ by Dr. R. K. Bansal. We will simulate our chain link by applying load in ANSYS and study the stress distribution (on circular portion as well as straight portion of the chain link).

Assumptions:
While finding out the value of stress analytically, we have made certain assumptions. We have assumed that the stress in certain regions is constant which will not be the case in the actual system. We have made sections like the inner part of the circular region, outer pat of circular region, inner and outer part of straight region. We consider the stresses in these parts to be constant for simplification …show more content…
We have neglected the effects due to friction and the stresses induced due to heating effects. regions where stresses are considered constant
The chain link we have modelled is as shown in the figure.

Modelling of the chain link has been done in Solidworks. We then imported this chain link in ANSYS Workbench. As the chain link is symmetric in many ways, we used only a part of the chain link for our analysis. The cut portion of the chain link is as shown in the figure.

We have fixed the end of the straight (fixed support) portion and applied the load to the inner region of the circular portion as shown in the

products, but selling is only a small fraction of marketing. As the term "Marketing" may replace "Advertising" it is the overall strategy and function of promoting a product or service to the customer. From a societal point of view, marketing is the link between a society’s material requirements and its economic patterns of response. Marketing satisfies these needs and wants through exchange processes and building long term relationships. The process of communicating the value of a product or service…
