Engineering Materials

Credit Hours: 

3
This course covers the design of mechanical and automotive components against fatigue failure. It covers mechanical properties and behavior of engineering materials subjected to static, dynamic, creep, and fatigue loads under environments and stress states typical of service conditions: biaxial theories of failure; behavior of crack bodies, microstructure-property relationships; design methodologies for homogeneous and composite materials. Major topics include: review elementary stress analysis, complex stress analysis: principle stresses in 3D; Mohr’s circle, elastic deformation; Hook’s Law, mechanism and rhelogical modeling; plastic, creep, and anelastic strain in metals and Polymers, failure theories for ductile and brittle materials, application of failure theories, introduction to LEFM (linear elastic fracture mechanics), fatigue (introduction), fatigue-stress raisers, S-N curve and design, strain based fatigue analysis, application of LEFM to fatigue, fatigue crack growth behavior, failure design using LEFM, creep: introduction, creep: life estimates, stress-strain time relations.

Use Your Cell Phone as a Document Camera in Zoom

  • What you will need to have and do
  • Download the mobile Zoom app (either App Store or Google Play)
  • Have your phone plugged in
  • Set up video stand phone holder

From Computer

Log in and start your Zoom session with participants

From Phone

  • Start the Zoom session on your phone app (suggest setting your phone to “Do not disturb” since your phone screen will be seen in Zoom)
  • Type in the Meeting ID and Join
  • Do not use phone audio option to avoid feedback
  • Select “share content” and “screen” to share your cell phone’s screen in your Zoom session
  • Select “start broadcast” from Zoom app. The home screen of your cell phone is now being shared with your participants.

To use your cell phone as a makeshift document camera

  • Open (swipe to switch apps) and select the camera app on your phone
  • Start in photo mode and aim the camera at whatever materials you would like to share
  • This is where you will have to position what you want to share to get the best view – but you will see ‘how you are doing’ in the main Zoom session.
