The engineering stress was then calculated by dividing the applied load by the original cross- sectional area. These adjusted figures for the Polycarbonate sample are plotted in a graph below alongside our calculated stress-strain curve. Discuss any possible error occurred during experiment. Excel will also produce the equation of the trendline for us. Moreover, the consideration of putting the test specimen on the universal testing machine —Instron Series is also important. The gage length of each specimen was determined to be 80 mm. Hence it can be seen that mild steel has high tensile strength compared to aluminium. There were a few small surface scratches on our Carbon Steel sample.

There was not a uniform area near the fracture due to necking and jaggedness of the break. True strain is calculated by dividing the change in length by the instantaneous final length.

tensile test procedure for steel

Toughness: It is the amount of energy per volume that a material can absorb before rupturing. This is because the stress-strain curve shows that it takes only 5mm of the tensile extension before the sample completely fractures.

First, if the specimen slips at all, while in the grips of the testing machine, it can alter the collected data. These results exactly match the behavior of HIPS as observed under tensile loading conditions.

Mc- Graw Hill Series. Precipitation hardening done to aluminium and its alloys hinders the elongation of the specimen. Ductility: It is a measure of how much strain a material can take before rupturing. Each plastic type was run at two different tensile extension speeds: 2 inches per minute, and 20 inches per minute.

Because of its high yield stress, we are able to minimize the size of the Carbon Steel cylindrical rod. The HDPE plastic is a polyethylene thermoplastic that is made of petroleum. It is also harder and more opaque and can withstand higher temperatures.
