I want you to write one page for Design of experiments and one page for analysis and one page for discussion
•Pick 5 materials to rank through an experiment
•2 materials that will likely work
•2 materials that you believe will likely not work
•1 material that will definitely not work
•Choose an experiment (ie tensile test, bending test, hardness test, etc.) that will be used to evaluate the materials for the application
•You will find the results of the test from published data
•Matweb, google scholar
•Choose one emphasis to rank your materials through
•Price, weight, or manufacturability, or choose your own
•These are not material properties, but other qualities of the matierial
•Best material will be chosen through the experimental data and the emphasis analysis.
Evaluate materials for:
•A prosthetic liner for a below-the-knee amputee triathlete
•Swim / Bike / Run
•Durability, temperature, air permeability, moisture
•A ski or snowboard
•Which material properties are important?
•Temperature ranges, wear, weight
•A J-shaped prosthetic for running
•Flexibility, resilience, weight
•Sustain repeated impacts
•Or…Whatever you feel passionate about!
•Must be related to materials in a commercial device
•May be related to sports, prosthetics, or whatever!
•Design of Experiments
•Choose your application
•Clearly define experiment
•State go / no-go criteria for materials with justification. These are your engineering requirements.
•Define your emphasis (price, manufacturability, weight, comfort, etc.)
•Clearly state material requirements with regards to this emphasis.
•List materials to be “tested”
•Analysis
•Provide real data relating to your experiment
•Provide real data relating to your emphasis
•Please include your sources in a “References” section at the end of the report
•Discussion
•Choose the best material, using results in the analysis section as justification
•Include and explain at least one relevant equation in your analysis
•Identify a structure/property/processing relationship
Format:
Design of Experiments
•Introduction
•What is the application?
•What is the general function of materials in this application?
•Experiment
•What experiment will you use to assess the materials?
•What information will this give you, and what is the threshold for which the material will be suitable?
•Factor of safety?
•Emphasis
•Define emphasis, justify, and give a threshold for which materials will be suitable.
•Be as specific as possible (using a quantifiable metric is best)
Format: Analysis and Discussion
•Analysis
•Be concise and accurate
•Figures must have captions
•Provide data for all 5 materials
•Discussion
•Does not need to be long
•Must incorporate experimental data and emphasis in the justification for the material deemed to be the best
