 L. Liu, B. Yi, T. Wang, Z. Li, J. Zhang, and G. H. Yoon. Additive Manufacturing 47 (2021): 102275.     A physical driven method for constructing functionally graded lattice structure is proposed by extending the conventional Solid Isotropic Material with Penalization (SIMP) method with linear buckling load factors and total volume constraints rather than intr...

G. H. Yoon. Computers & Structures 256 (2021): 106637.     The present research contributes in the structural topology optimization with the manufacturing limitation called the overhang constraint and the optimization of the anisotropic material properties. For the optimization with self-supporting structure, the overhang-free shadow filter method is developed. To consid...

R. Sivapuram, R. Picelli, G. H. Yoon, and B. Yi. Computer Methods in Applied Mechanics and Engineering 384 (2021): 114000.     This paper presents a framework for the discrete design of optimal multimaterial structural topologies using integer design variables and mathematical programming. The structural optimization problems: compliance minimization subject to&nbs...

M. Takalloozadeh and G. H. Yoon. Engineering Computations 38, no. 8 (2021): 3174-3192.     Body forces are always applied to structures in the form of the weight of materials. In some cases, they can be neglected in comparison with other applied forces. Nevertheless, there is a wide range of structures in civil and mechanical engineering in which weight or other types of b...
