Tensile Test Review Improve your schematics Improve your figures by Microsoft Excel

1. ME354 Tensile Test Review Improve Your Lab Report Yih-Yan Lin Feb.4, 2011 • Tensile Test Review • Improve your schematics • Improve your figures by Microsoft Excel • Improve your figures by MATLAB • Improve your tables by Microsoft Word

2. Tensile Test Review Data Analysis of Lab 4 — Tensile Test Load Strains * Statistical Analysis (average and standard deviation) ** Pick up only one set of the data *** Error Analysis Use appropriate schematics, tables and figures in your report.

3. Tensile Test Review – MATLABCode examples Engineering stress and strain curves Modulus of Toughness Enlarge the pictures to see the details.

5. Improve Your Figures by Microsoft Excel Excel Default Figure 5 2 7 9 8 6 1 3 2 4 Inside major tike mark type Must have axis labels and units Keep decimal places consistent Change axis color form grey to black Remove horizontal grid line No chart area border Need plot area border Move the legend inside the plot area No markers

6. Improve Your Figures by Microsoft Excel (cont’) What are you going to tell your readers? Ultimate Strength: Steel > Al Modulus of Toughness: Steel > Al Modulus of Elasticity: Steel > Al Yielding Strength: Steel ~ Al A36 Steel 6061 T-6 Aluminum Failure Strain Ultimate Strength

7. Improve Your Figures by Microsoft Excel (cont’) 2. Decimal place 1. Greek alphabet: “Times New Roman” to “Symbol” Font style: Times New Roman Font style: Symbol 4. Change to black axis (default is gray color) A36 Steel 1. Greek alphabet 3. Inside tick mark type 6061 T-6 Aluminum 4. Axis color: solid and black PMMA Polycarbonate 3. Inside tick mark type 2. decimal place:1 1. Greek alphabet • No horizontal grid lines. (You may keep both horizontal and vertical grid lines or remove both of them, • but don’t keep either one) • Remember axis labels and units. (physical parameter, Greek alphabet, unit . eg: Stress s (MPa) ) • If you don’t have color printer, use black color, gray color and different line styles to distinguish different data sets. • Either “legend” or “text box in the plot” will suffice to help distinguish different data sets.

8. Improve Your Figures by Microsoft Excel (cont’) Looks good, but could be better. • Distinguished by types of line style and types of data-point • symbol– either one of them would suffice. • Textboxes by the line might be better than legend.

9. Improve Your Figures by Microsoft Excel (cont’) • Different data sets are distinguished • by types of line style. • Types of data-point symbol are only • for showing numbers of data point. • Different data sets are distinguished • by types of data-point symbol. • Lines are only for showing the trend • of the data.

10. Improve Your Figures by MATLAB MATLAB Default Figure – much better than Word 106M,10-6m Decimal places inconsistent Unit, Legend and Textbox Different line styles to distinguish different data sets

11. Improve Your Figures by MATLAB (cont’) Arrows and textboxes MATLAB code Legend and different line style

12. Improve Your Tables by Microsoft Word No unit Word Default Figure Avoid two rows in a unit This table has Times New Roman, Calibri and italic, three font styles. Improve your Figure Only three full-width lines; no vertical lines Table E.6. Stress and Strain at Strain Gage 2 for C-Channel. Title Headings Body • Use “Times” font style. Avoid “Calibri” and “italic”. Use “italic” only when you emphasize something, • refer to a book name or show writing style. Italic may help Greek alphabets look better. • Keep font size and font style consistent in your report. • Don’t forget the units. • Keep decimal place consistent and decimal place more than three might be meaningless
