CEE 300 / TAM 324: Lab 1 Tension Test Worksheet Lab section: Student name: General note: use space as needed. The answer length is not suggested by the space. Q1 (5 pts). Construct a diagram of engineering stress vs. strain for each of the materials tested using plotting software, e.g. Excel, MATLAB, Origin, etc. The tab-delimited ASCII data files contain, in order, the crosshead position, the load, the strain, and the time. (For details, see lab manual Appendix B.) For ductile materials, select one strain scale such that only the elastic portion of the curve is emphasized; use the data in this range to determine modulus of elasticity. Then select a second strain scale that allows the entire curve to be included on your plot. For brittle materials, one scale is usually sufficient. Additionally, superimpose the stress-strain diagram for each material onto a single graph (with the exception of PMMA) using an appropriate strain scale.
