Three basic types of materials were used in the experiment. They were a) mild steel (low carbon), b) copper, and c) duralumin. They had different properties; therefore they had different tensile strengths and elongations. Aims

Abstract The tensile test is widely used to provide basic design information on the strength of materials and as an acceptance test for the specification of materials. The teaching and learning of tensile testing was based on laboratory experiments used in the Mechanical Engineering Laboratory (CM180) at the City University. The experiment looked at how the microstructure of a material can affect its properties. It also introduced tensile testing and stress-strain curves. It is done by using of a tensile testing machine. Three basic types of materials were used in the experiment. They were a) mild steel (low carbon), b) copper, and c) duralumin. They had different properties; therefore they had different tensile strengths and elongations. Aims On completion of this experiment one should be able: a) To understand the general shape of the tensile stress-strain curve. b) To understand how the microstructure of a material can affect its properties, in particular the yield-strength...
