Out of the three materials tested, the steel 1045 exhibited the most elastic properties, with it being able to deform elastically for a greater amount of stress than for the other specimens, as indicated by its stress-strain curve as shown in figure 1, and further supported by it having the highest modulus of elasticity of all three specimens, as shown in table 2. The mild steel specimen had the second greatest modulus of elasticity, and the aluminium specimen had the lowest modulus of …show more content…
A published value on the modulus of resilience could not be located.
The published values for the mild steel specimen are, Modulus of elasticity = 200GPa (AZO Materials 2013a), Yield Strength = 250MPa (AZO Materials 2013a), Tensile Strength= 400-550MPa (AZO Materials 2013a), Ductility based on elongation=23%( AZO Materials 2013a), and ductility based on area of reduction = 15% (AZO Materials 2013a). A published value on the modulus of resilience could not be located.
The published values for the aluminium specimen are, Modulus of elasticity= 68.9GPa (ASM Incorporated n.d.), Yield Strength= 276MPA (ASM Incorporated n.d.), Tensile Strength= 310MPa (ASM Incorporated n.d.), Ductility based on elongation = 17% (ASM Incorporated n.d.).
