Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Nearing completion of risk reduction and individual component analysis
Accomplishments from Previous Week
Met with Prof. Tustaniwskyj for week 10 meeting
Clarified that for loading determination, we will seek to find the loads on the base hinge as well as the pin instead of simplifying the whole hinge as a rectangular prism
(Jason) Found the loadings on the two key components of hinge
(Nathan) Established methods to use for calculating yield safety factor
(Kelly) Constructed a stress-strain curve for composite and identified important material properties.
Slides of this have been added
(Roy) Served as primary contact for sponsors and vendors. Was advised by professor and sponsor to put less focus on fatigue research
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Finish components of risk reduction presentation
Add slides of FBDs and loading calculations (Jason)
Add slides of failure criteria methods and safety factor calculations (Nathan)
Add slides of stress-strain curve and material properties of stainless steel for comparison (Kelly)
Add slides on discussion of fatigue failure, less focus on analysis (Roy)
Finish individual component analysis
Types of composites, compare given composite to other similar ones (Jason)
Types of pin designs (material, size, etc.) (Roy)
Types of inserts (screws, threaded inserts, etc.) (Kelly)
FEA software (ANSYS, ABAQUS, Solidworks Simulation) (Nathan)
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments
Clarified about questions on loading and stress concentrations
Focus on uni-directional loading in the relevant service load direction for comparison between the two materials
Realize that pin will still be metallic in the composite hinge assembly; focus more on gload design stresses instead of focusing on concentration regions
Said that fatigue analysis is not of significance, reaffirming what professor said
Established that we would discuss characteristics of fatigue since it is a potential failure mode but not go too in-depth with analysis
Instructor Comments from Last Meeting and Actions Taken to Address these Comments
Concern about fatigue discussion in risk reduction, similar to sponsor
Established that we would discuss characteristics of fatigue since it is a potential failure mode but not go too in-depth with analysis
Risks and Areas of Concern (i.e. show stoppers)
Limitations of team/sponsor/professor contact due to coronavirus
Resources or Information Required but not Available

Schedule
Finish risk reduction and individual component analysis by end of Monday
Hold remote meeting on spring quarter logistics (team-only, with sponsor, with professor)
Budget (list amount spent and amount remaining)
$0 of $2800 spent
Progress on Report and Webpage
Updated project management page and finals week report.
