Abstract: Abstract. We present a new topology optimization method implemented in acusolve© software for the optimal design of devices in the presence of fluid flow and heat transfer. Topology optimization is used to determine the ...

Abstract: A reliability-based topology optimization (RBTO) approach is presented using a new mean-value second-order saddlepoint approximation (MVSOSA) method to calculate the probability of failure. The topology optimizer uses a ...

Abstract: This paper proposes a new second-order saddlepoint approximation (SOSA) method for reliability analysis of nonlinear systems with correlated non-Gaussian and multimodal random variables. The proposed method overcomes the ...
