Tension test is widely used to provide a basic design information on the strength of materials and is an acceptance test for the specification of materials. The major parameters that describe the stress-strain curve obtained during the tension test are the tensile strength (UTS)‚ yield strength or yield point (σy)‚ elastic modulus (E)‚ percent elongation (∆L%) and the reduction in area (RA%).

Abstract A tensile test was conducted on an Instron tensile machine using a 3/16 inch copper rod. Using data acquired stress and strain was calculated and plotted on Excel to analyze stress strain curve. Modulus of elasticity‚ 0.2% yield stress‚ ultimate tensile stress and % elongation were also calculated. Introduction A tension test is probably the most fundamental type of mechanical test you can perform on material. Tensile tests are simple‚ relatively inexpensive‚ and fully standardized

element tensile test is conducted for element size of 5mm at strain rates mentioned in Fig. 7 7. The true stress versus plastic strain results of the simulation in comparison to the load curve is shown in Fig. 7 9. As the damage is coupled to the stress tensor by Eq. 4 1‚ there is a continuous reduction of stress.
