Unformatted text preview: , Thermal Stress Analysis (ANTYPE = 0) Element Type(s): 2-D Spar (or Truss) Elements (LINK1) Input Listing: vm3.dat Test Case Find the stresses in the copper and steel wire structure shown below. The wires have a cross-sectional area of A. The structure is subjected to a load Q and a temperature rise of ∆T after assembly.
