Topology design of thermomechanical actuators combined with heat source optimization
(Yokohama Publishers, 2019-11)
In the paper a problem of optimal topology and shape design of thermo-mechanical actuators with the heat source support is considered. The objective is to maximize the output displacement in a prescribed direction on the ...
Topology design of thermomechanical actuators
(Springer, 2017-05)
The paper deals with topology design of thermomechanical actuators. The goal of shape optimization is to maximize the output displacement in a given direction on the boundary of the elastic body, which is submitted to a ...
Aeroelastic Analysis of a Typical Section Using of Shape memory wire actuator
(2011)
Shape memory alloys (SMAs) provide a compact and effective actuation for a variety of mechanical systems. In this paper, a numerical simulation study of a three degree of-freedom airfoil, subjected to two-dimensional ...
Design of bi-metallic devices based on the topological derivative concept
(Pergamon-Elsevier Science Ltd., 2015-01)
In this work the topological derivative concept is applied in the context of topology design of thermo-mechanical devices, where the linear elasticity system (modeled by the Navier equation) is coupled with the steady-state ...
