Bimetallic Strip Under Thermal Load

Simulation Setup

Material:

Upper strip:

• isotropic: Ea
  $E_a$

   

  = 200 GPa, ν

  $\nu$

   

  = 0, ρ

  $\rho$

   

  = 7870 kg/m³, κ

  $\kappa$

   

  = 60 W/(mK), γa

  ${\gamma }_a$

   

  = 1e-5 1/K, Reference temperature = 300 K

Lower strip:

• isotropic: Eb
  $E_b$

   

  = 200 GPa, ν

  $\nu$

   

  = 0, ρ

  $\rho$

   

  = 7870 kg/m³, κ

  $\kappa$

   

  = 60 W/(mK), γb

  ${\gamma }_b$

   

  = 2e-5 1/K, Reference temperature = 300 K

Initial Conditions:

• uniform: To
  $T_o$

   

  = 300 K

Constraints:

• Node N1 fixed in all directions
• Node N2 fixed in x and y direction
• Node N3 fixed in y direction

Temperature:

• T
  $T$

   

  = 400 K on face ABCD and EFGH

Contact:

• Bonded contact with automatic ‘Position tolerance’ between two strips.
