Which type of Analysis should be considered for the two different materials cooling homogeniously?

  I had 2 different materials with different coefficient of thermal expansion (material with coefficient of thermal expansion alpha1 is kept inside the material with coefficient of thermal expansion alpha2). The bulk material is cooling homogeneously from 720 degrees to 20 degrees. All structural properties are taken as constant for both materials (not varying with time) but youngs modulous and poissions ratio of both materials are different.
  Only temperatures are varying i.e cooling homogenously to room temperature. I would like to visualize the stresses that will develope due to different thermal expansions of two materials which are cooled homogenously from 720 to 20 degrees.
  (Like at time 1 --> 720 , time 2 sec --> 719, time 3 sec --> 718 degrees etc...)
  
  Whick kind of Analysis could be done in Ansys. Like Ansys Static or Ansys Transient or Thermal analysis etc ?
  Any suggestions will be greatly helpfull.

  You can use a Static Structural Analysis with Thermal Condition boundary condition. The following videos might help:
