MATE 1104 TENSILE TEST LAB HANDOUT In your lab write-up please include the following: 1. Cover Page 2. Purpose 3. Calculations: Calculate the following for each graph: Area of test coupon Ultimate Tensile Strength 0.2% Offset Yield Strength % Elongation % Reduction of Area Modulus of Elasticity (1045 steel only) 4. Plot the Stress-Strain curve for the 44W sample by hand You are given the Load-Strain curve for the 44W sample You must convert the Load-Strain curve to Stress-Strain Show a sample calculation for determining the stress value at a particular load Create a data table to indicate the loads and the corresponding stress values and its strain value 5. Label each graph (44W and 1045 steel) with the following: Ultimate tensile strength (UTS) Yield Point (44W only) Proportional Limit (1045 material only) 0.2% offset yield strength Elastic Region Plastic Region Title of Graph 6. Results/Discussion Discuss what the effect of carbon content has on each material. b. Determine what the converted Rockwell hardness would be for each material (refer C. to page. 10 in course pack 2589) What can be said regarding the mechanical properties (ductility, strength & hardness) of each material?
