A: Find the ultimate tensile strength (Rm), which is the maximum load/original cross-sectional area in MPa. (Remember the graph is Force vs Elongation, so you need to convert your readings to stress and strain). B: Find the proportional limit (Rp), which is the point at which stress and strain are no longer related to each other in a linear relationship C: Find the elastic limit (Re), which is the greatest stress that a material can support without permanent deformation. D: Determine the Young's Modulus (E), which is the slope of the linear elastic portion (or Hooke's line) of the stress - strain curve in GPa) E: Find the yield point, the stress level at which plastic deformation begins. It can be determined as the initial departure from linearity of the stress - strain curve. Mark it on the graph. F: Find the offset yield stress (proof stress), established by which a straight line is drawn parallel to the elastic portion of the stress-strain curve at a specified strain offset, usually 0.002. G: Find the modulus of resilience (Ur), which is the capacity of a material to absorb energy when it is elastically deformed in J.m-3. It can be determined from the area under the elastic region of the stress - strain curve.Tensile Testing of Materials Force Value, F [kN] Tensile Testing of Materials 32.00 28.80 25.60 22.40 19.20 16.00 12.80 9.60 6.40 3.20 0.00 0.00 1.50 3.00 Material Tensile Diagram 4.50 X-5.975; Y=26.152 6.00 7.50 9.00 Traverse Displacement, AL [mm] 10.50 12.00 F 08.83 kN dl=09.48 mm 13.50 15.00 Simulation Control: Test Material: Str.
