Abstract

Tensile testing is an important tool for evaluating fundamental properties of engineering materials, and is critical in developing and controlling the quality of materials, as well as their selection and application in engineering. However, commercial tensile testing machines with the required capabilities are prohibitively not cost effective or user friendly. In addition, they are extremely bulky, so they take up a considerable amount of space and cannot be moved or relocated once they are fixed and calibrated for a position. This study designed and fabricated a single column 200 N, electric powered tensile testing machine, suitable for evaluation of strength properties of non-ferrous metals and their alloys. It was intended to be used for laboratory experiments in Kenule Beeson Saro-Wiwa Polytechnic, Bori. It consists of a mild teel frame, a load cell, lead screw, weighing machine, extensometer, and two bevel gears, with a maximum stroke of 100 mm having vertical motion. The machine is driven by a 1 hp single phase induction stepper motor. The fabricated machine was tested for performance evaluation by conducting tensile test with different aluminium samples. The result revealed an increase in stress value with increased strain, and a linear range at low strain for the sampled aluminium, followed by a transition into a plastic zone up to the breaking point at a strain of 1.5–3.0%. Also, the obtained test results were compared with those from standard commercial tensile testing machine for similar test samples and the error was calculated and found to be less than 10%. The fabricated machine is therefore suitable for evaluation of strength properties of non-ferrous metals and their alloys as well as polymers and composite materials.
