TL;DR: In this paper, the influence of heat convection and internal heat generation on structural designs is investigated. But the authors focus on the influence on the heat transfer coefficient and heat conduction on the structure surface.

TL;DR: In this article, a new structural optimization method based on the level set method using a new geometry-based re-initialization scheme where both the numerical analysis used when solving the equilibrium equations and the updating process of the level-set function are performed using the Finite Element Method.

TL;DR: In this article, a new topology optimization method for designing vibrating structures that targets desired eigenfrequencies and eigenmode shapes is proposed, which is applicable to the design of mechanical resonators and actuators.

TL;DR: In this article, a robust topology optimization method for compliant mechanisms is proposed, where the effect that variation of the input load direction has on the output displacement is considered, with the variance evaluated using first-order derivatives.

TL;DR: In this article, a reliability-based topology optimization method for frame structures that considers uncertainties in applied loads and nonstructural mass at the early conceptual design stage is proposed, where the effects of stiffness and eigenfrequency on system reliability are evaluated by regarding them as a series system, where mode reliabilities can be evaluated using firstorder reliability methods.
