Dear Dan, I have to model and show the deformation pattern that was observed in an experiment conducted on a block of 18x14x1.5mm with a coating of another 2 layers 0.165mm and .023 mm(each layer of different material properties). The block when subjected to a repeated 2000 thermal cycles (ONE CYCLE - 1._at_Time 0, 24 degree C 2. _at_Time 10 min, Temp 700C, _at_Time 70, Temp 700C, 4. _at_Time 80, Temp 24C.)showed deformation at the edges. I am trying to simulate it in ANSYS... How do i do it? Regards, Samgopiraj Yadav, MS - Mechanical Engineering, Tennessee Technological University Cookeville.
