~ 2019 [22] Topological design of heat dissipating structure with forced convective heat transfer
관리자 2023-12-20 91

G. H. Yoon. Journal of Mechanical Science and Technology 24, no. 6 (2010): 1225-1233.     This paper discusses the use of the topology optimization formulation for designing a heat dissipating structure that utilizes forced convective heat transfer. In addition to forced convection, there is also natural convection due to natural buoyancy forces induced by local heating insi...

관리자 2023-12-20 87

G. H. Yoon. Computer Methods in Applied Mechanics and Engineering 199, no. 25-28 (2010): 1744-1763.     This study uses model reduction (MR) schemes such as the mode superposition (MS), Ritz vector (RV), and quasi- static Ritz vector (QSRV) methods, which reduce the size of the dynamic stiffness matrix of dynamic structures, to calculate dynamic responses and sensitivity val...

~ 2019 [20] Topology optimization for stationary fluid–structure interaction problems using a new monolithic formulation
관리자 2023-12-20 113

G. H. Yoon. International journal for numerical methods in engineering 82, no. 5 (2010): 591-616.     This paper outlines a new procedure for topology optimization in the steady-state fluid–structure interaction (FSI) problem. A review of current topology optimization methods highlights the difficulties in alternating between the two distinct sets of governing equations ...

~ 2019 [19] Maximizing the fundamental eigenfrequency of geometrically nonlinear structures by topology optimization based on element connectivity parameterization
관리자 2023-12-20 112

G. H. Yoon. Computers & structures 88, no. 1-2 (2010): 120-133.     This paper pertains to the use of topology optimization based on the internal element connectivity parameterization (I-ECP) method for nonlinear dynamic problems. When standard density-based topol- ogy optimization methods are used for nonlinear dynamic problems, they typically suffer from two main numer...

~ 2019 [18] Theoretical aspects of the internal element connectivity parameterization approach for topology optimization
관리자 2023-12-20 130

G. H. Yoon, Y. Y. Kim, M. Langelaar, and F. van Keulen. International journal for numerical methods in engineering 76, no. 6 (2008): 775-797.     The internal element connectivity parameterization (I-ECP) method is an alternative approach to overcome numerical instabilities associated with low-stiffness element states in non-linear problems. In I-ECP, elements are connected ...

~ 2019 [17] A monolithic approach for topology optimization of electrostatically actuated devices

G. H. Yoon and O. Sigmund. Computer Methods in Applied Mechanics and Engineering 197, no. 45-48 (2008): 4062-4075     This paper presents a new topology optimization scheme for nonlinear electrostatic systems actuated by Coulomb’s forces. For successful optimization, computational issues such as (i) alternating governing equations with respect to spatially defined desig...

~ 2019 [16] Minimum scale controlled topology optimization and experimental test of a micro thermal actuator
관리자 2023-12-20 93

S. Heo, G. H. Yoon, and Y. Y. Kim. Sensors and Actuators A: Physical 141, no. 2 (2008): 603-609.     This paper is concerned with the optimal topology design, fabrication and test of a micro thermal actuator. Because the minimum scale was controlled during the design optimization process, the production yield rate of the actuator was improved considerably; alternatively, the...
