Geometry of nanoindentation cube-corner cracks observed by FIB tomography: Implication for fracture resistance estimation (Elsevier, 2015-09-01)
Restricted access - publisher's policyWhen indenting a brittle material with a sharp indenter, cracks can be generated at the corners of the imprint. From the length of these cracks, the fracture resistance can be estimated. This technique is simple and allows ...

Restricted access - publisher's policyThe use of Optical Backscatter Reflectometer (OBR) as a distributed fiber optic system to measure strain and detect cracking in concrete structures is investigated. A laboratory experience in a concrete slab is first ...
Numerical homogenization for composite materials analysis: comparison with other micro mechanical formulations (2015-04)
Restricted access - publisher's policyThis work presents a two-scale homogenization procedure to analyze three dimension composite structures by FEM. The theory implemented is compared with other micro-structural formulations: micro models and serial parallel ...
(Universitat Politècnica de Catalunya, 2013-05-13)
Open AccessTo numerically simulate a failure process, damage models can be used. In order to avoid mesh dependency problems of local damage models, nonlocal models are employed. The use of nonlocal displacements is an efficient ...
(Centre Internacional de Mètodes Numèrics en Enginyeria (CIMNE), 2014)
Restricted access - publisher's policyThis work investigates systematically strain localization and failure mechanics for elastoplastic damage solids. Two complementary methodologies, i.e., traction-based discontinuities localized in an elastic solid and strain ...
Restricted access - publisher's policyCable-stayed bridges are highly statically redundant, light and flexible structures. This complexity highlights the role of the structural system identification (SSI) method in the calibration of the actual properties of ...
