The magnitude and the distribution of stresses in bi-metal thermostats subjected to uniform heating or cooling are determined. The suggested approach enables one to evaluate the normal stresses in the thermostat plates, as well as the shearing and normal (“peeling”) stresses in the interface. The developed approach is applicable, generally speaking, to any elongated lap shear assembly.
