Quantum continuum mechanics made simple [PDF]

open access: yesThe Journal of Chemical Physics, 2012
In this paper we further explore and develop the quantum continuum mechanics (QCM) of Tao et al. [Phys. Rev. Lett. 103, 086401 (2009)] with the aim of making it simpler to use in practice. Our simplifications relate to the non-interacting part of the QCM equations, and primarily refer to practical implementations in which the groundstate stress tensor ...

Analysis of high velocity impacts of quasibrittle material fragments with a Hopkinson bar [PDF]

open access: yesEPJ Web of Conferences, 2021
In this work it has been characterized the impact behaviour of quasibrittle fragments against a Hopkinson bar in a wide range of impact velocities (70-180 m/s). Hopkinson bar is designed to measure the impact forces thanks to a proper instrumentation. In

Experimental analysis of high velocity impacts of composite fragments on aluminium plates [PDF]

open access: yesEPJ Web of Conferences, 2021
The improvement of engines is one of the ways to diminish the fuel consumption in civil aircrafts, and Open Rotors engines are one of the best promises in order to achieve a sensible efficiency increment.

Feed-Forward Neural Networks for Failure Mechanics Problems

open access: yesApplied Sciences, 2021
This work addresses an efficient neural network (NN) representation for the phase-field modeling of isotropic brittle fracture. In recent years, data-driven approaches, such as neural networks, have become an active research field in mechanics.
