Increasing loads were applied while staying right below the yield points. A every load, te force value as well as the extensometer reading was recorded. Te recorded data was used for calculations. O each metal, sme load was exerted. Ater calculating aluminium, te following were confirmed: yeld stress was 314.47 MPa, te ultimate tensile stress was 341.47MPa, te true stress at fracture was 605.63MPa, te breaking stress was 266.89Mpa, %L (percentage of elongation) was 15. 8percent and the percentage area reduction was 55. Te calculation of copper yielded results: te yield stress was 255.89MPa, te ultimate tensile stress was 319.40 MPa, te breaking stress was 198.04MPa, te true stress at fracture was found to be 745.84MPa, te percentage of elongation or the %EL calculated to 15.

8percent and the percentage area reduction was 73. Wthin the second part of this experiment, a extensometer was made use of to measure the strain caused elongation within the region of elasticity. Fr both the copper and the aluminum, agraph for stress against strain was calculated and plotted. Te outcome slope the relative stiffness (the elasticity young modulus) for both the copper and the aluminum metals.

Te young’s modulus of elasticity for the copper material was 156. Te young’s modulus of elasticity for the aluminum material was 303. Ater comparison between the copper and the aluminum in terms of strength and ductility, iteresting correlations between the fracture surfaces and the results measured were observed. In the order of increasing the tensile strength and decreasing of the ductility, cpper was ranked higher followed by aluminum. Tese results do agree with values callister.

Amajor difference of between two hundred percent (200%), ad three hundred percent (300%) between the calculated values or calculated data and the values that are published was revealed. I proved difficult to select an alloy composition with which to compare the data, hwever, nt many values do correspond in whatever form. Te young modulus of elasticity tensile strength, yeld strengths as well as the percentage of elongation values for both the copper and the aliminium found in the first experiment and the second experiment were different the values within the Callister text book anywhere from two hundred percent to three hundred percent depending. ..
