Multi-physics Assignment #3: Due March 12 by 5pm. Every student in class will be modeling one type of material. Please find the appropriate material properties for you material and list them in your report and state the source (which textbook, matweb, etc.). Part 1: Create an axisymmetric elastic model of spherical contact against a rigid flat that includes electrical conduction, but not joule heating or heat transfer. Use the meshing methodology we discussed in class. (A) Assume that the sphere is 1 mm in diameter and perform a mesh convergence for the case of an interference of ω c . (B) Apply 1 Amp and 10 Amps of current and apply an evenly distributed range of 10

Unformatted text preview: interferences up to 100 c . Save the results and the code. Create a table of the contact resistance (Voltage drop) and contact radius versus force and interference for all cases. Please submit these files with your report. (C) Plot and compare this to the Hertz elastic model discussed in class: Part 2: Repeat Part 1, but for an elastic-plastic contact (including yield strength). Use the elastic-plastic model discussed in class to make a comparison. R E S C y c 2 2 ⎟ ⎟ ⎠ ⎞ ⎜ ⎜ ⎝ ⎛ ′ ⋅ ⋅ = π ρ R R electrical 4 =...
