Static stress-strain relationship of material

Abstract

This Final Year Project(FYP) presents the work of project number B323, Static Stress-Strain

Relationship of material. N3.1-B2-01, the Material Lab 1 of Nanyang Technological University

(NTU) is the venue where the student conducted all the experiments related to this project.

The purpose of this report is to give the reader an overview of this FYP. This project is an

enhancement to the previous project, Standard Static Tensile, Compression and Torsion Tests

done by Teng Chen Yuen.

Static tensile testing is a very common technique used to measure the ultimate tensile strength

and the INSTRON machine is able to manage a crosshead speed of 0-510mm/min. The static

tensile test is based on the force applied on the specimen per unit area as measured by the load

cell and the strain by extensometer.

The objective of the project is to ensure the INSTRON 5500R machine accuracy and reliability in

testing for other materials. In order to achieve that, the student has to calibrate the tensile

machine with standard Aluminum alloy specimen AL6061-T6 and comparing the calibration

results with the past research results.

The project will also look into the causes and solution of the problems faced during the

experiment. Several recommendations for the static tensile test will be discussed in order to

improve the accuracy and reliability of the static tensile test.
