Abstract
In this paper, different implementations of numerical locally reacting boundary conditions are studied for acoustic problems. In this comparative study we analyze two types of equations, the Euler equations and the wave equation. We also analyze both finite-differences time-domain [...]Abstract
Gradient-enhanced models based on regularised displacements are an alternative to standard models in order to simulate material failure. In this alternative formulation, mechanical displacements u coexist with smoothed displacements u˜, which are the solution of a diffusion-reaction [...]
