Fatigue analysis of a naval composite structure
(CRC Press, 2020)
Conference report
Restricted access - publisher's policyThe use of composite materials in marine industry has many potential benefits, such as lower weight. However, there are still some failure mechanisms, such as fatigue, that are not yet completely under- stood. This work ... -
A transonic potential solver with an embedded wake approach using multivalued finite elements
(International Centre for Numerical Methods in Engineering (CIMNE), 2021)
Conference lecture
Open AccessA potential transonic solver with an embedded wake is presented. The flow outside of attached boundary layers of streamlined bodies flying at high Reynold numbers can be assumed to be irrotational and isentropic. This ... -
Mechanical and environmental behavior of cement mortars containing ladle furnace slag
(2020)
Conference lecture
Open AccessAt present, steel production is mainly done in basic oxygen furnaces (BOF) and electric arc furnaces (EAF) (Pauliuk, S. et al, 2013, Morfeldt, J. et al, 2015). According to the statistics, it is expected that the use of ... -
Numerical modelling of two-phase flow in fractured rock masses using zero-thickness interface elements
(International Centre for Numerical Methods in Engineering (CIMNE), 2021)
Conference report
Open AccessIn recent years, the authors and co-workers have developed a 3D finite element model for coupled thermo-hydro-mechanical (THM) problems in fractured rock masses. Zero-thickness interface elements are used for taking into ... -
Iterative strategies based on constitutive dissipation
(International Centre for Numerical Methods in Engineering (CIMNE), 2021)
Conference report
Open AccessFE formulation of solid mechanics problems typically require iterative strategies to solve the resulting nonlinear system. Basic strategies with prescribed load values, such as the Newton-Raphson method, are not valid in ... -
New results in 3D-mesomechanical coupled analysis of external sulphate attack in concrete
(International Centre for Numerical Methods in Engineering (CIMNE), 2021)
Conference report
Open AccessExternal Sulphate Attack (ESA) is one of the main degradation processes affecting concrete structures. It takes place when the concrete is in an environment rich in sulphate ions and with a high humidity index. Once it has ... -
Effect of long-term pore pressure evolution on the integrity of cement plugs of abandoned oil wells in CCS sites
(International Centre for Numerical Methods in Engineering (CIMNE), 2021)
Conference report
Open AccessIn the context of Carbon Capture Storage (CCS) in abandoned hydrocarbon reservoirs, a preliminary study of the effects of pore pressure evolution on the integrity of oil-well cement seals is performed. A 2D cross-section ... -
Transient large heat advection in fractured rock: a zero-thickness interface formulation
(International Centre for Numerical Methods in Engineering (CIMNE), 2021)
Conference report
Open AccessIn a fractured rock mass, the existence of discontinuities may generate preferential paths where the hydraulic flow velocities are frequently much higher than in the porous medium and heat advection tends to dominate over ... -
Environmental impacts of hot, warm, half warm and cold recycled bituminous mixtures
(European Asphalt Pavement Association (EAPA), 2021)
Conference report
Restricted access - publisher's policyFor some years, reducing bituminous mix temperatures has been a common trend among asphalt producers because it is a very effective way to reduce energy consumption and atmospheric emissions of asphalt plants, along with ... -
Procedure for the evaluation and comparison of the cracking resistance of bituminous mixtures. Characteristic curve. Fénix diagram
(European Asphalt Pavement Association (EAPA), 2021)
Conference lecture
Restricted access - publisher's policyThe particularity of the bituminous materials is that their break is ductile and tough. They require a great energy to produce the break since the start (maximum load) until failure. In traditional mechanical tests, only ... -
Effects of tailings viscosity on liquefaction triggering analyses
(University of Alberta, 2021)
Conference report
Restricted access - publisher's policyRecent analyses have suggested that creep or rate effects may be present in some tailings and can play a role in triggering liquefaction failure. However, the role of creep in liquefaction triggering analysis of tailing ... -
Evaluation of transport events with the use of big data, artificial intelligence and augmented reality techniques
(2021)
Conference report
Restricted access - publisher's policyThe phenomenon of "smart cities" generalizes the use of Information and Communication Technologies. The generation and use of data to manage mobility is a challenge that many cities are betting on and investing in. Through ...
