Finite crystal elasticity of carbon nanotubes based on the exponential Cauchy-Born rule
Arroyo Balaguer, Marino; Belytschko, T. (2004-03)
Article
Accés obertA finite deformation continuum theory is derived from interatomic potentials for the analysis of the mechanics of carbon nanotubes. This nonlinear elastic theory is based on an extension of the Cauchy-Born rule called the ... -

Force transduction and lipid binding in MscL: a continuum-molecular approach
Vanegas, Juan Manuel; Arroyo Balaguer, Marino (2014-12-01)
Article
Accés obertThe bacterial mechanosensitive channel MscL, a small protein mainly activated by membrane tension, is a central model system to study the transduction of mechanical stimuli into chemical signals. Mutagenic studies suggest ... -
Fourth order phase-field model for local max-ent approximants applied to crack propagation
Amiri, Fatemeh; Millán, Daniel; Arroyo Balaguer, Marino; Silani, Mohammad; Rabczuk, Timon (2016-12)
Article
Accés obertWe apply a fourth order phase-field model for fracture based on local maximum entropy (LME) approximants. The higher order continuity of the meshfree LME approximants allows to directly solve the fourth order phase-field ... -
Fracture toughening and toughness asymmetry induced by flexoelectricity
Abdollahi Hosnijeh, Amir; Peco, Christian; Millán, Daniel; Arroyo Balaguer, Marino; Catalan, Gustau; Arias Vicente, Irene (2015-09-08)
Article
Accés restringit per política de l'editorialCracks generate the largest strain gradients that any material can withstand. Flexoelectricity (coupling between strain gradient and polarization) must therefore play an important role in fracture physics. Here we use a ... -
Geometric derivation of the microscopic stress: a covariant central force decomposition
Torres Sánchez, Alejandro; Vanegas, Juan Manuel; Arroyo Balaguer, Marino (2016-08)
Article
Accés obertWe 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 ... -
High-order maximum-entropy collocation methods
Greco, Francesco; Arroyo Balaguer, Marino (2020-08-01)
Article
Accés obertThis paper considers the approximation of partial differential equations with a point collocation framework based on high-order local maximum-entropy schemes (HOLMES). In this approach, smooth basis functions are computed ... -

Hydraulic fracture and toughening of a brittle layer bonded to a hydrogel
Lucantonio, Alessandro; Noselli, Giovanni; Trepat Guixer, Xavier; Arroyo Balaguer, Marino; DeSimone, Antonio (2015-10-28)
Article
Accés obertBrittle materials propagate opening cracks under tension. When stress increases beyond a critical magnitude, then quasistatic crack propagation becomes unstable. In the presence of several precracks, a brittle material ... -
Hydraulic fracture during epithelial stretching
Casares, Laura; Vincent, Romaric; Zalvidea, Dobryna; Campillo, Noelia; Navajas, Daniel; Arroyo Balaguer, Marino; Trepat Guixer, Xavier (2015-03-01)
Article
Accés obertThe origin of fracture in epithelial cell sheets subject to stretch is commonly attributed to excess tension in the cells' cytoskeleton, in the plasma membrane, or in cell-cell contacts. Here, we demonstrate that for a ... -
Hydraulic fracturing in cells and tissues: fracking meets cell biology
Arroyo Balaguer, Marino; Trepat, Xavier (2017-02-01)
Article
Accés obertThe animal body is largely made of water. A small fraction of body water is freely flowing in blood and lymph, but most of it is trapped in hydrogels such as the extracellular matrix (ECM), the cytoskeleton, and chromatin. ... -
Hydraulic fracturing in cells and tissues: fracking meets cell biology
Arroyo Balaguer, Marino; Trepat Guixer, Xavier (2017)
Article
Accés obertThe animal body is fundamentally made of water. A small fraction of this water is freely flowing in blood and lymph, but most of it is trapped in hydrogels such as the extracellular matrix (ECM), the cytoskeleton, and ... -
Importance of force decomposition for local stress calculations in biomembrane molecular simulations
Vanegas, Juan Manuel; Torres Sánchez, Alejandro; Arroyo Balaguer, Marino (2014-02-01)
Article
Accés obertLocal stress fields are routinely computed from molecular dynamics trajectories to understand the structure and mechanical properties of lipid bilayers. These calculations can be systematically understood with the ... -
Interplay of packing and flip-flop in local bilayer deformation. How phosphatidylglycerol could rescue mitochondrial function in a cardiolipin-deficient yeast mutant
Khalifat, Nada; Rahimi Lenji, Mohammad; Bitbol, Anne-Florence; Seigneuret, Michel; Fournier, Jean Baptiste; Puff, Nicolas; Arroyo Balaguer, Marino; Angelova, Miglena I. (2014-08-19)
Article
Accés obertn a previous work, we have shown that a spatially localized transmembrane pH gradient, produced by acid micro-injection near the external side of cardiolipin-containing giant unilamellar vesicles, leads to the formation ... -
Local maximum-entropy approximation schemes: a seamless bridge between finite elements and meshfree methods
Arroyo Balaguer, Marino; Ortiz, Michael (Wiley and Sons, 2006-03)
Article
Accés obertWe present a one-parameter family of approximation schemes, which we refer to as local maximum-entropy approximation schemes, that bridges continuously two important limits: Delaunay triangulation and maximum-entropy ... -
