This research applies the reliability-based topology optimization (RBTO) method to a heat transfer problem. The design problem is formulated to minimize the structural volume subject to the reliability constraint concerning thermal problem under variation on coefficient of heat transfer. The topology optimization uses level set boundary expressions based on the concept of the phase field method for obtaining clear boundary shapes. The topology optimization is combined with the reliability-based optimization method that is formulated as a single loop algorithm by using Single Loop Single Variable (SLSV) method to reduce computational time. Through numerical example, difference between the optimum configurations on deterministic method and reliability-based method is demonstrated and the effectiveness of this method is discussed.
