Special Issue Information

Dear Colleagues,

Structural topology optimization is a powerful computational design method that seeks the most efficient material distribution within a specified design domain to meet performance requirements. Some well-established algorithms are Solid Isotropic Material with Penalization (SIMP), Bi-directional Evolutionary Structural Optimization (BESO), the level-set method, Moving Morphable Components (MMCs), Floating Projection Topology Optimization (FPTO), and Smooth-Edged Material Distribution for Optimizing Topology (SEMDOT). As a critical branch of lightweight design, topology optimization plays a prominent role across aerospace, automotive, civil, and defense industries. Advancements in both the theory and application of topology optimization are essential to drive innovation within the field. Despite extensive efforts by researchers to advance the theory and application of topology optimization, several challenges remain to be addressed.

This Special Issue aims to bring together researchers from diverse backgrounds to share their insights and findings. The Guest Editor welcomes all methodologies capable of addressing specific optimization challenges, with no preference for any particular algorithm. Topics for this Special Issue include, but are not limited to, algorithm and software development, design for manufacturing, lattice structure design, engineering and artistic applications, parallel computing, and AI-driven topology optimization.

The Guest Editor invites researchers working in these areas to contribute their latest work in the form of original research and review articles. Papers that present novel algorithms or applications, as well as those providing numerical validations of topologically optimized designs, are particularly encouraged.

Density variables based on nodal or Gaussian points are naturally incorporated in meshless topology optimization approaches, pursuing distinct topological layouts with solid and void solutions. However, engineering applications have been hampered by the fact that the authentic structure boundary cannot be identified without manual intervention. To alleviate this issue, the Smooth-Edged Material Distribution for Optimizing Topology (SEMDOT) method is developed within the context of meshless approximation. In meshless analysis, the non-overlap cell variables instead of nodal or Gaussian-based variables are adopted to characterize the existence or absence of sub-regions. This work proposes a non-penalized SEMDOT where an interpolation-based heuristic sensitivity expression is utilized. The 2D and 3D compliance minimization problems serve to validate the efficiency and applicability of the proposed non-penalized SEMDOT approach based on the framework of the meshless method. The numerical results demonstrated that the proposed approach is capable of generating final designs with continuous and smooth edges or surfaces. Full article
