EFFECTS OF PLASTIC DEFORMATION ON TENSILE TEST SPECIMENS BY VARIATIONS IN THE STRAINING RATE
Abstract
The effect of strain rate in the plastic range on the percent elongation, percent reduction of area, and the rise in specimen temperature due to straining 5052-0 Al alloy, AZ80A Mg alloy and annealed SAE 4130 steel was determined. Eleven specimens of SAE 4130 steel which were heat treated to approximately 200,000 psi were also tensile tested at various strain rates to determine how the rise in temperature due to straining compared with the annealed SAE 4130 steel specimens. It was found that strain rate in the plastic range had no significant effect on the percent elongation or percent reduction of area properties of the materials tested. The increase in temperature due to increased strain rates was greater for the SAE 4130 steel heat treated to 200, 000 psi than for the annealed 4130 steel, but in neither case did it significantly affect the percent elongation or percent reduction of area properties.
