COURSE TITLE: ENGINEERING LABORATORY III (BDA 27101)
TOPIC 1: TENSILE TEST
1.
INTRODUCTION
The tensile experiment is the most common mechanical test that reveals several important mechanical properties, such as: modulus of elasticity, yield strength, ultimate tensile strength, ductility, and toughness. The material to be tested is formed into a shape suitable for gripping in the testing machine, and then pulled at constant rate until it fractures. The tensile instrument elongates the specimen at a constant rate and has devices to continuously measure and record the applied load and elongation of the specimen. During the stretching of the specimen, changes occur in its physical dimensions and its mechanical properties. The ability to predict the loads that will cause a part to fail depends upon both material properties and the part geometry. This experiment involves testing to determine the relative properties.
2.
OBJECTIVES
1. To understand the principles of tensile testing machine.
2. To observe the stress-strain relationship for several standard materials by performing a tensile test.
3. To obtain approximate values from stress-stain curve such as percentage of elongation, Yield Strength; Tensile Strength and Modulus of Elasticity, E.
3.
LEARNING OUTCOMES
At the end of this experiment, students should be able to:
1. Conduct experiment and identify the dependent and independent variables.
2. Record, tabulate and analyze the raw data.
3. Indicate the important parameters such as yield strength, elastic, plastic region, maximum load, failure load and explain each parameter.
4. Determine the modulus of elasticity for each specimen.
5. Understand the stress-strain relationship for several standard materials by performing a tensile test and tensile
