Sampling-based stochastic analysis of the PKN model for hydraulic fracturing
(2019-02)
Article
Accés obertHydraulic fracturing processes are surrounded by uncertainty, as available data is typically scant. In this work, we present a sampling-based stochastic analysis of the hydraulic fracturing process by considering various ... -
Small-scale gravitational instabilities under the oceans: implications for the evolution of oceanic lithosphere and its expression in geophysical observables
(2008-10)
Article
Accés obertSublithospheric small-scale convection (SSC) is thought to be responsible for the flattening of the seafloor depth and surface heat flow observed in mature plates. Although the existence of SSC is generally accepted, its ... -
Solution of geometrically parametrised problems within a CAD environment via model order reduction
(2020-01-01)
Article
Accés obertThe main objective of this work is to describe a general and original approach for computing an off-line solution for a set of parameters describing the geometry of the domain. That is, a solution able to include information ... -
Subduction dynamics and the origin of Andean orogeny and the Bolivian orocline
(2011-11-23)
Article
Accés restringit per política de l'editorialThe building of the Andes results from the subduction of the oceanic Nazca plate underneath the South American continent1. However, how and why the Andes and their curvature, the Bolivian orocline, formed in the Cenozoic ... -
The effects of compositional and rheological stratifications on small-scale convection under the oceans: implications for the thickness of the oceanic lithosphere and seafloor flattening
(2008-10)
Article
Accés obertPressure-release melting at mid-ocean ridges generate compositional and rheological layering in the oceanic mantle that may control the evolution of the oceanic lithosphere. We use dynamic models coupled with melting and ... -
The effects of small-scale convection in the shallow lithosphere of the North Atlantic
(2021-12-01)
Article
Accés obertCurie point depth can be used as a proxy for plate temperatures. Data from the North Atlantic (10°–50°N) are used here to determine if the observed oscillations and patterns in Curie depths could be a subproduct of small-scale ... -
The main factors and rules of stress shadow of perpendicular cracks
(2017-07)
Article
Accés restringit per política de l'editorialBased on elasticity theory, we use numerical Galerkin finite element discretization method and implement Matlab finite element code to simulate “stress shadow” distributions of mutual orthogonal fractures. The principal ... -
The subductability of continental lithosphere: the before and after story
(2011)
Article
Accés obertThe temporal evolution of internal forces in a collision environment controls first-order characteristics such as convergence rate, slab dip, subduction stall, and slab breakoff, amongst others. Foremost among these forces ... -
Towards real time assessment of earthfill dams via Model Order Reduction
(2022-02-01)
Article
Accés obertThe use of Internet of Things (IoT) technologies is becoming a preferred solution for the assessment of tailings dams’ safety. Real-time sensor monitoring proves to be a key tool for reducing the risk related to these ... -
Using reduced basis approximation for efficient surrogate-based inverse identification of thermo-hydro-mechanical parameters from an in situ heating test
(Springer Nature, 2022-06-27)
Article
Accés obertIn this paper, a reduced-order model built from the reduced basis (RB) method is used as a surrogate for an inverse identification problem related to coupled thermo-hydro-mechanical (THM) processes. The RB space—spanned ... -
Verification of reduced-order models for real-time applications with haptic feedback
(CIMNE, 2015)
Text en actes de congrés
Accés obertReal-time simulation systems equipped with haptic peripherals, like those employed in virtual surgery or industry lay-out design, require feedback rates on the order of 1kHz. Such an impressive requirement for a simulation ...
