I. Description of the Elasticity Project
Design and load a 2D rectangular bar with modulus E=2GPa, the Poisson’s ratio v=0.4.
Task1 (40%). To perform numerical uni-axial tension test on a 2D rectangular bar made of the material given, by using any Finite Element (FE) software. Please choose plane stress and plane strain elements, respectively. Output engineering stress-strain curves on one plot. Also, output stress and strain contours. Comparing the results from the plane stress and plane strain element models.
Task2 (30%) Demonstrate the differences between plane stress and plane strain, using the theory/criteria we learned in class together with the FE results.
Task3 (30%). To design and load a structure in elastic range, output the stress and strain contours with an overall tensile or compression or shear strain of 2% (you choose the loading based on your interests)
Groups: 1-3 students/group
Components: (1) Topic slides and presentation
2 slides + ~5-minute presentation (including Q&A, demonstrating FE models, only model not the results) in Task 1, and your design idea in Task 3. (no models/results are needed, simply explaining what your design is and why you are interested in this design)
(2) Oral presentation (~10 slides) ~15-mins, including Q&A
Deadlines:
• Topic presentation: slides due 8AM, 02/25 (Tu.) (30 points)
• Oral Presentation: slides due 8AM, 03/18 (Tu.) (70 points)
II. Oral Presentation Guidelines
1. General tips for presentations
• Clearly state your topic. At the very beginning of your talk, remind the audience of the topic that you will present today.
• Clearly organize your presentation. It should be obvious to the audience what you are going to present and the structure for the presentation. You may wish to include a table of contents. (Actually, the best talks have a clear structure but omit the table of contents slide from the presentation.)
• Provide clear and informative visual aids. Please make sure the slides are easily readable, and are not overly cluttered with unnecessary colors, patterns, and graphics.
• Don’t read your presentation. If you use slides, they should aid and not replace speech. Minimize the use of written words.
• Provide a summary or conclusion at the end. Lead into the discussion by emphasizing the state of the science on this topic and some of your key discussion points.
• Stick to the time allotted foryour presentation and discussion.
• Be enthusiastic. Act like you believe that your topic is the most important issue ever.
• Practice your presentation beforehand. This will familiarize you with the material, give you a sense of timing, improve the flow of your talk and your communication with your audience, and help you get back on track when you get interrupted with a question.
• Anticipate likely content questions and prepare a response in advance.
• Be attentive and polite, and enthusiastically participate in the discussion. Don’t be afraid to say something wrong. Try to be constructive when asking questions.
III.Project Report Guidelines
A report is required to describe the final project. The goal of this report is to improve your scientific writing. The content, presentation, and style. of the report should be similar to what you would submit to a journal or as your thesis. As such, the report must be type-written and presented in an organized and neat manner. The report will include 3-5 figures with a length of ~5 pages (the main body, not including the references, table of content etc.).
The report should be organized approximately as follows. There is a bit of discretion in writing scientific papers, so you may decide to organize individual reports slightly differently. However, please include the following components:
Title: it summarizes the purpose of the exercise and reflects the factual content of the paper. A good title is straightforward and uses keywords that researchers in a particular field will recognize.
Abstract: In a concise paragraph of approximately 100 to 200 words, summarize the goal of the study, purpose, key result(s), and major discussion points. (The purpose of an abstract is to allow the reader to judge whether it would serve his or her purposes to read the entire report.)
Introduction: The introduction defines the subject of the report. Outline the scientific purpose(s) or objective(s) for the research performed, and give the reader sufficient background to understand the rest ofthe report. Briefly discuss why this issue is important. Briefly summarize previous knowledge relevant to the study question. End the introduction with a sentence or two that summarize the overall scientific goal of the exercise, and your approach to investigate it.
Methods/Design: Describe the method you used. Provide a description of your design, analytical and/or finite element model, list necessary equations, schematics, drawings etc. Please make the description in sufficient details that readers could repeat the research presented.
Prediction Results: Summarize the data from the analysis without discussing their implications. Display your results in one or more table(s) and figure(s), and quantitatively describe important observed trends. Organize the section based on type of data. Provide confidence intervals/uncertainty for observations, and significance levels for conclusions.
Conclusion and/or discussion: Summarize and consider implications of your main design. Discuss whether the data support the hypothesis and the expectations that were described in the introduction. Explain conclusions that can be made from the results and the significance of these conclusions.
Literature cited: List all sources that were cited in the text using a consistent format style. The listing should be alphabetized by the last name of the first author, or as a numerical list.
Supplementary materials (optional): Additional figures, analysis, results which support the main text.
