Abstract:

Numerical simulation tests of bimetallic-disk thermostate were performed under varied temperature using finite element analysis, in which the geometric nonlinearity has been considered. These numerical tests provided some data concerning the influence of differemt .size of disk and material property on the radial stress/strain amplitude. A study was also carried out on the up-switch temperature drift due to delamination within the roll bond interface.

Key words: bimetallic, buckle, finite element, thermostat
