This work presents a first numerical study for the density-based topology optimisation in the challenging and scarcely explored context of nonlinear electromechanics, focusing on electro-active polymers, capable of undergoing large electrically induc

In this work we analyze the behavior of the spectrum of the peridynamic fractional p-Laplacian, $$(-\Delta _p)_{\delta }^{s}$$ , under the limit process $$\delta \rightarrow 0^+$$ or $$\delta \rightarrow +\infty $$ . We prove spectral convergence to

We present a mathematical model of topology optimization for non-local linear diffusion equation. The model provides a rigorous and constructive answer to the challenge of interpreting sensitivity filtering as an internal feature of a specific contin

In this work we introduce volume constraint problems involving the nonlocal operator $(-\Delta)_{\delta}^{s}$, closely related to the fractional Laplacian $(-\Delta)^{s}$, and depending upon a parameter $\delta>0$ called horizon. We study the associa

This paper aims to present an elegant way to design multimodal piezo transducers, i.e., piezoelectric sensors/actuators that succeed in filtering a set of desired eigenmodes among those belonging to a bigger set prescribed beforehand. That can be eff

Topology optimization can be used to design piezoelectric actuators by simultaneous design of host structure and polarization profile. Subsequent micro-scale fabrication leads us to overcome important manufacturing limitations: difficulties in placin
