Title: Materials


1
Materials Mechanics Laboratory
  • Report Writing

Geoffrey Fisher and Ryan Breighner Texas Tech
University Spring 2008
2
Lab Reports
  • 3 of these throughout the semester
  • Completed as a group with your lab partners

3
The Report As A Whole
  • - 1 margins on all sides (note different than
    word default) -
  • - Size 12 font -
  • - Arial or Times New Roman -
  • - Double spaced -
  • - All pages will have a page number except for
    the title page and the table of contents -
  • Page numbers centered at bottom of page -
  • Section Headings are left justified, bold, in
    same font as body of report -
  • Number your equations with parentheses and define
    the variables
  • e.g. F ma (1)
  • Avoid personal pronouns
  • e.g., The force was applied rather than We
    applied the force

4
The Sections
  • Title Page
  • Table of Contents
  • Abstract
  • List of Figures
  • List of Tables
  • Introduction

6
Table of Contents
  • Length lt1 page

7
Abstract
  • Length ½ to ¾ of a page
  • Page number is i
  • Brief summary of objective and major results
  • Be quantitative
  • No figures, tables, references, or equations
  • - It helps to write this last

8
List of Figures
  • - Length varies
  • - Only necessary if more than one figure is used
  • - Reference the figure in the text before showing
    it
  • The label Figure 1 is written below the
    figure (no space between figure and label)
  • Cite all figures not generated by you or your
    group
  • Page number is ii

9
List of Tables
  • Length varies
  • Same rules that apply to List of Figures apply
    here with one difference
  • The label Table 1 is written above the table
    rather than below it
  • Page number is iii

10
Introduction
  • Length 1½ to 2 pages
  • Page number is 1
  • Be general rather than specific to your
    experiment
  • Write in present tense
  • Purpose is to provide background and motivate the
    reader

11
Introduction (cont.)
  • Provide theoretical background of experiment
  • Advantages and disadvantages of methods used
  • Relevant equations
  • Cite references

12
Methods Materials
  • Length 1 to 2 pages of text
  • Describes purpose and function of equipment used
  • Include labeled schematic or photograph
  • Model name and company (short form can be used
    after initial naming)
  • e.g., initial Instron 8500 tensile testing
    machine, afterwards Instron machine or
    tensile testing machine

13
Methods Materials (cont.)
  • Be concise
  • When writing procedure, write in chronological
    order
  • Use past tense
  • Be quantitative when possible
  • e.g., A load of 50 N was applied rather than
    A load was applied
  • For experiments with repetition, dont rewrite
    the entire procedure
  • Do not simply list the steps (outline format is
    unacceptable)

14
Results
  • Length 1 page (excluding tables, figures,
    equations)
  • Quantitative results
  • Summarize in text of report
  • Use tables and graphs
  • Graphs included should be representative (put
    additional graphs in an appendix)
  • Compare with published values if possible
  • Discuss any manipulation of data and include
    relevant formulas

15
Discussion
  • Length 1 to 1½ pages
  • Discuss
  • Major results
  • Explanation of results
  • Validity of results
  • Sources of error
  • State any future recommendations

16
References
  • Length varies
  • List every reference cited in text here
  • List in alphabetical order (authors last name)
  • Two ways to cite within the report
  • Authors last name and publish year (Smith, 2003)
  • Reference number 1
  • Format for 1st method on Reference page
  • Smith, William. Foundations of Materials Science
    and Engineering, 3rd edition. McGraw-Hill, 1993.
  • Format for 2nd method on Reference page
  • 1 Smith, William. Foundations of Materials
    Science and Engineering,
  • 3rd edition. McGraw-Hill, 1993.

17
Appendices
  • Length varies
  • Sample calculations
  • Data sheet from lab
  • Additional Figures

18
Equations
  • Equations are numbered so they can be referenced
    in text (see below)
  • Use Microsoft Equation Editor, MathCAD or LaTeX
    to generate your equations
  • Should look like
  • NOT
  • n1-(1/rk-1)(((rk)-1)/(k(rc-1)) (1)
