Stress-constrained topology optimization for compliant mechanism design
TL;DR: In this paper, a stress-constrained topology optimization approach for compliant mechanism design is presented, where the maximum stress is approximated using a normalized version of the commonly-used p-norm of the effective von Mises stresses.
Aeroelastic tailoring using fiber orientation and topology optimization
TL;DR: In this article, a structural optimization aided design methodology for composite laminated plates subject to fluid-structure interaction is presented, where the goal of the optimization procedure is to increase the flutter speed onset through the maximization of natural frequencies related to the vibration modes involved in the phenomenon.

Topology optimization of embedded piezoelectric actuators considering control spillover effects
TL;DR: In this article, a coupled finite element model of the structure is derived assuming a two-phase material and this structural model is written into the state-space representation, and the optimization of the shape and placement of the conventionally embedded piezoelectric actuators are performed using a sequential linear programming (SLP) algorithm.

Stress-based topology optimization of compliant mechanisms design using geometrical and material nonlinearities
TL;DR: It is shown that material nonlinearity plays an important role for stress constraint problems and the use of a projection scheme helps to obtain optimized topologies with a high level of discreteness.

Simultaneous optimization of piezoelectric actuator topology and polarization
TL;DR: In this article, a coupled finite element model of the structure is derived assuming a two-phase material, and this structural model is written into the state-space representation to determine the distribution of piezoelectric material which maximizes the controllability for a given vibration mode.
