The aim of this test case is to validate the following functions:
thermomechanical solver with different materials
The simulation results of SimScale were compared to the analytical results derived from [Roark]. The mesh used was created locally consisting of quadratic hexahedral elements and uploaded to the SimScale platform.
Bonded contact with automatic ‘Position tolerance’ between two strips.
The equation (1), (2), (3) and (4) used to solve the problem is derived in [Roark]. Equations (2) and (3) are the displacements of the bimetallic strip in x and z direction respectively. Whereas, equation (4) is the normal stress in x direction at the bottom surface.
Comparison of the x and z displacements computed on node N3 and σxx
