Direct shear test lab report pdf

Lap Report

Each student must submit an individual technical laboratory report on the experiment they carried out. Please see ‘Laboratory Report’ handout for guidance on writing a laboratory report. You will be expected to consult the appropriate British Standards and comment on the accuracy of the work undertaken. In addition, your comments should include the potential applications of the test results in building and civil engineering practice. The use of spreadsheets and word processing in the calculation of the laboratory test results and the write up of the experiment will be actively encouraged. Each student will also have to include a Risk Assessment and Safe Working Procedure as part of their laboratory report. The marks will be issued as follows:

1) A Laboratory Report – for both the Shear box and Triaxial experiments: • See next page ‘Laboratory Report’ 80 marks

2) Key skills • Safe Working Procedure and Risk Assessment* 10 marks • Presentation of report# 5 marks • Library use (reference to published results/BS) 5 marks

*For the Shear Box and Triaxial laboratory experiments #Please ensure that you include the standard university coursework coversheet detailing your full name, ID, name of lecturer, name of the experiment, date, etc. You must upload your laboratory work to Turnitin, via the icon for this module on My-Beckett, and obtain an ‘originality report’. This Turnitin originality report must be included at the start of your laboratory report. Failure to include it will result in a default mark of zero being awarded. NB you can only upload one document in a 24-hour period, i.e. to prevent you from ‘tweaking’ the report the night before it is due in. If a high percentage is returned in the ‘similarity index’ you will be investigated regarding plagiarism/collusion. NB the software can detect similarities between your report and your colleagues, as well as published literature (whether paperbound or web-based); hence do not copy! Normal University rules regarding late submissions shall apply. An attendance Register will be taken at the Laboratory Sessions, and THE RULE IS: NO ATTENDANCE – NO MARK. Any work submitted by people who do not attend, will NOT be marked. The laboratory report must be submitted with the relevant lecturer’s name written clearly on the first page. Failure to comply with this format could result in your work being marked late or even lost – students should always retain a copy of their submitted coursework until they have received their original piece of coursework back, which has been marked. This work must be submitted by:

- Full-time students: 13/12/18 @ 9.00am

- Part-time students: 13/12/18 @ 9.00am

LABORATORY REPORT

TITLE PAGE (Part of presentation marks) (1) Title of Experiment (2) Name of student, ID no., course, module, level (BSc/BEng), & mode of study (e.g. PT/FT) (3) Group & Date of performing the experiment (4) Lecturer’s name

TURNITIN ORIGINALITY REPORT

Failure to include this report will result in a default mark of zero being awarded.

ABSTRACT (10 marks) Summarises essential aspects of the report: (1) The purpose of the experiment (2) Key findings (3) Significance (4) Major conclusions

INTRODUCTION (10 marks) Explain very briefly the purpose of the experiment and important background/theory. The introduction should be more focussed than the abstract, stating the subject matter of the report clearly and concisely, in a few sentences.

EXPERIMENTAL PROCEDURE (5 marks) Only note down anything that you did different than what is quoted in the laboratory handout and/or the corresponding BS (describe the process in chronological order). However, include a detailed hand sketch of the apparatus, which is fully labelled.

CALCULATIONS AND RESULTS (20 marks) Show only one typical calculation on the data obtained from the experiment and then tabulate the results of your analysis - spreadsheets. Present the analysed data in figures or tables to indicate what knowledge has been gained from the experiment. Include a labelled hand sketch to show the failure of the sample(s) tested.

DISCUSSION (20 marks) Points to consider when writing the discussion (the most important part of your report): • Are your values of the right order of magnitude, i.e. are they in keeping with typical values

in textbooks? What does your textbook say about the materials relevant to this experiment? • Could the experiment be improved? • According to theory, how should the material behave - how did it behave? • What has the experiment taught you about the material you were testing? • What have you learned? Quotations from textbooks are perfectly acceptable provided that the whole report is not copied from a book and also provided that the source of the information is acknowledged.

CONCLUSIONS (10 marks) Be brief. The conclusions should be concise statements, which arise from your discussion - they can be negative or positive.

REFERENCES/LIBRARY USE (5 marks) - Harvard/Numeric style (including the date of accessing any website) APPENDIX I (5 marks) - Raw data and calculations – no comments required. APPENDIX II (5 marks) - Safe Working Procedure APPENDIX III (5 marks) - Risk Assessment Presentation (5 marks) - The laboratory report must be word processing and graphs produced on Excel and labeled correctly, and include a title page as detailed above, etc.

NOTES ON LABORATORY REPORT

Note: write the report in the third person

ABSTRACT

The abstract often also includes a brief reference to theory or methodology. The abstract should be one or two paragraphs of 100-200 words. For example: This experiment examined the effect of………………….... The test was to determine…………... Five samples were tested ……………. Each condition was ……………... Results showed that ……………………….. This last result is contrary to theory/expectations………………. . These results have important on……………

INTRODUCTION

Example: The purpose of this experiment was to identify …………………………. These were determined using the ????? method/machine. Note: • The experiment is already finished. Use the past tense when talking about the

experiment. "The objective of the experiment was..." • The report, the theory and permanent equipment still exist; therefore, these get the

present tense: "The purpose of this report is...", "Newton’s Law is ..." & "The triaxial produces…"

EXPERIMENTAL PROCEDURE

As noted above.

CALCULATIONS AND RESULTS Note: (1) Number and Title tables and graphs (Table - title at top, Figure - title at bottom; both

starting from 1.1, 1.2..., 2.1, 2.2..., etc. for each section) (2) Use a sentence or two to draw attention to key points in tables or graphs (3) Provide sample calculation only (4) State key result in sentence form DISCUSSION Points to consider: (1) Compare expected results with those obtained - if there were differences, how can you

account for them? Saying "human error" implies you're incompetent. Be specific; for example, the instruments could not measure precisely, the sample was not pure or was contaminated, or calculated values did not take account of friction.

(2) Analyse experimental error - Was it avoidable? Was it a result of equipment? If an experiment was within the tolerances, you can still account for the difference from the ideal. If the flaws result from the experimental design explain how the design might be improved.

(3) Explain your results in terms of theoretical issues - Often undergraduate labs are intended to illustrate important physical laws. Usually you will have discussed these in the introduction. In this section move from the results to the theory. How well has the theory been illustrated?

(4) Relate results to your experimental objective(s) - If you set out to identify an unknown, state the answer.

(5) Compare your results to similar investigations - In some cases, it is legitimate to compare outcomes with classmates, not to change your answer, but to look for any anomalies between the groups and discuss those.

(6) Analyze the strengths and limitations of your experimental design - This is particularly useful to demonstrate your understanding of the experiment.

CONCLUSIONS Note: (1) State what is known (2) Justify statement (3) State significance (4) Suggest further research REFERENCES As noted above.
