Topology Optimization for Minimum Compliance with Material Volume and Buckling Constraints under Design-Dependent Loads

Yuanteng Jiang et al.

Summary: Stability is critical in structural design. This study proposes a model to solve the problem of buckling-constrained topology optimization under design-dependent loads. The Kreisselmeier-Steinhauser aggregation function is used to reduce multiple constraints to a single one. The proposed optimization algorithm, based on finite element and sensitivity analyses, is proven effective and reliable through numerical examples.

Compliance-based topology optimization of structural components subjected to thermo-mechanical loading

Ticho Ooms et al.

Summary: In the construction industry, thermal gradient can subject structural components to internally restrained thermal expansion, which can alter the mechanical response in structural topology optimization. In this paper, a density-based topology optimization procedure is developed for compliance minimization of structural components under thermo-mechanical loads. The proposed procedure takes into account the influence of design-dependent temperature field and thermal properties, and its effectiveness is demonstrated on the MBB problem with thermal loading.

The reformulated Koiter-Newton method for thermal-mechanical buckling and postbuckling analysis of thin-walled structures

Ke Liang et al.

Summary: This paper reformulates the reduced-order modeling method for geometrically nonlinear thermal-mechanical analysis of thin-walled structures. A thermal load is treated as an independently unchanged load, and the internal force space is expanded to include mechanical load, thermal load, and predefined perturbation loads. A thermal-mechanical reduced-order model is constructed, and a path-following scheme is proposed to trace the entire geometrically nonlinear thermoelastic response.

Evidence theory-based reliability optimization for cross-scale topological structures with global stress, local displacement, and micro-manufacturing constraints

Lei Wang et al.

Summary: This study presents an uncertainty-oriented cross-scale topology optimization model with global stress reliability constraint, local displacement constraint, and micro-manufacturing control based on evidence theory. The model designs the material distribution of both the macrostructure and the cell microstructure for a two-dimensional porous material structure. The uncertainty parameters are processed using evidence theory to evaluate the reliability of the structural strength performance.

A feature-driven robust topology optimization strategy considering movable non-design domain and complex uncertainty

Zeshang Li et al.

Summary: With the increasing diversification of engineering structure performance requirements and the continuous refinement of processing and manufacturing, structural design faces more factors to be considered. This study proposes a feature-driven robust topology optimization strategy considering movable non-design domain and complex uncertainty. It quantifies the influence of non-design domain and uncertainty on structural topology, analyzes the mathematical properties of structural response, and derives the sensitivity of the optimization model, providing a basis for gradient-based optimization algorithms.

Three-dimensional thermal buckling analysis of functionally graded material structures using a modified FSDT-based solid-shell element

A. Hajlaoui et al.

Summary: This paper analyzes the thermal buckling behavior of functionally graded shell structures using a modified first-order enhanced solid-shell element formulation. Both temperature-independent and temperature-dependent material properties are considered, with shear strains accounted for through the thickness of the shell. Various methods are employed to address locking issues, and numerical results are validated with existing studies. The effect of different parameters on thermal buckling temperature is highlighted through solving numerous examples.

Topology optimization subject to additive manufacturing constraints

Moritz Ebeling-Rump et al.

Summary: Topology optimization aims to find the ideal material distribution for maximum stiffness in a structure subjected to external forces, using techniques such as volume constraints, additive manufacturing constraints, and Lagrangian methods to address instability issues during 3D printing. The additive manufacturing constraint helps create support structures at low computational cost, which can be finely tuned and improve stability in the printing process.

Summary: This paper demonstrates how a strain energy transition approach can be used to remove artificial buckling modes that often occur in stability constrained topology optimization problems. Through the use of nonlinear large deformation hyperelastic simulation, combined with Newton's method and eigenvalue analysis, as well as Helmholtz PDE-filter and method of moving asymptotes, the design optimization is successfully achieved, and the effectiveness of the method is validated through numerical examples.
