Abstract EN
This paper is to present a thermomechanical topology optimization formulation.
By designing structures that support specific nondesignable domain, optimization is to suppress the stress level in the nondesignable domain and maintain global stiffness simultaneously.
A global stress measure based on p -norm function is then utilized to reduce the number of stress constraints in topology optimization.
Sensitivity analysis employs adjoint method to derive the global stress measure with respect to the topological pseudodensity variables.
Some particular behaviors in thermomechanical topology optimization of elastic supports, such as the influence of different thermomechanical loads and the existence of intermediate material, are also analyzed numerically.
Finally, examples of elastic supports on a cantilever beam and a nozzle flap under different thermomechanical loads are tested with reasonable optimized design obtained.
