Continuum Mechanics for Engineers. Theory and Problems
(2017-03)
Book
Open AccessThis book was born with the vocation of being a tool for the training of engineers in continuum mechanics. In fact, it is the fruit of the experience in teaching this discipline during many years at the Civil Engineering ... -
Continuum mechanics modeling and simulation of carbon nanotubes
(2005-12)
Article
Open AccessThe understanding of the mechanics of atomistic systems greatly benefits from continuum mechanics. One appealing approach aims at deductively constructing continuum theories starting from models of the interatomic interactions. ... -
Continuum modelling using the Discrete Element Method. Theory and implementation in an object-oriented software platform
(Universitat Politècnica de Catalunya / Centre Internacional de Mètodes Numèrics en Enginyeria, 2012-07-28)
Minor thesis
Open Access[ANGLÈS] The Discrete Element Method is a relatively new technique that has nowadays and intense research in the field of numerical methods. In its first conception, the method was designed for simulations of dynamic ... -
Discretization influence on regularization by two localization limiters
(1994-06)
Article
Open AccessIn materials with a strain-softening characteristic behavior, classical continuum mechanics favors uncontrolled strain localization in numerical analyses. Several methods have been proposed to regularize the problem. Two ... -

Flexoelectricity at surface instabilities and stress singularities
(Universitat Politècnica de Catalunya, 2023-06-16)
Doctoral thesis
Open Access(English) The flexoelectric effect, the two-way linear coupling between strain gradient and electric polarization (direct flexoelectricity) or electric field gradient and strain (converse flexoelectricity) universally ... -
Geometric derivation of the microscopic stress: a covariant central force decomposition
(2016-08)
Article
Open AccessWe revisit the derivation of the microscopic stress, linking the statistical mechanics of particle systems and continuum mechanics. The starting point in our geometric derivation is the Doyle-Ericksen formula, which states ... -
Impact comminution of solids due to local kinetic energy of high shear strain rate: I. Continuum theory and turbulence analogy
(2014-03-01)
Article
Restricted access - publisher's policyThe modeling of high velocity impact into brittle or quasibrittle solids is hampered by the unavailability of a constitutive model capturing the effects of material comminution into very fine particles. The present objective ... -
Insights into the controversy over materials data for the comparison of biomechanical performance in vertebrates
(2015-03)
Article
Open AccessMechanical comparison of different species is performed with the help of computational tools like Finite Element Analysis FEA. In palaeobiology it is common to consider bone like an isotropic material for simulations but ... -
Mathematical and computational modeling of flexoelectricity at fixed and moving interfaces, fracture surfaces and contact
(Universitat Politècnica de Catalunya, 2023-09-08)
Doctoral thesis
Open Access(English) Flexoelectricity is a two-way coupling between strain gradient and polarisation or strain and polarization-gradient. Harnessing flexoelectricity as a functional property requires gradient engineering. This is a ... -
Mathematical and computational modeling of flexoelectricity at mesoscopic and atomistic scales
(Universitat Politècnica de Catalunya, 2021-03-01)
Doctoral thesis
Open AccessThis PhD thesis focuses on the development of mathematical and computational models for flexoelectricity, a relatively new electromechanical coupling that is present in any dielectric at the micron and sub-micron scales. ... -

(Iniciativa Digital Politècnica, 2012)
Book
Open AccessLa mecánica del medio continuo parte de la mecánica de sistemas de partículas que interaccionan para dar lugar a un modelo material, sólido o fluido, mucho más genérico que el de sólido rígido. La mecánica del medio continuo ... -
Mechanics reveals the biological trigger in wrinkly fingers
(2017-04)
Article
Open AccessFingertips wrinkle due to long exposure to water. The biological reason for this morphological change is unclear and still not fully understood. There are two main hypotheses for the underlying mechanism of fingertip ... -
Nonlinear continuum mechanics: an engineering approach

Book
Restricted access - publisher's policyThis book collects most of the lecture notes I have developed and I have been using in a course on Continuum Mechanics for the Master of Science Course on Computational Mechanics and the Master Course on Numerical Methods ... -
On the geometric character of stress in continuum mechanics
(2007-09)
Article
Open AccessThis paper shows that the stress field in the classical theory of continuum mechanics may be taken to be a covector-valued differential two-form. The balance laws and other fundamental laws of continuum mechanics may be ... -
