An experimental and numerical investigation on fatigue of composite and metal aircraft structures
Pitta, Siddharth; Rojas Gregorio, José Ignacio; Roure Fernández, Francisco; Crespo Artiaga, Daniel; Wahab, Magd Abdel (2022-04)
Article
Accés obertThe static strength and fatigue crack resistance of the aircraft skin structures depend on the materials used and joint type. Most of the commercial aircraft’s skin panel structures are made from aluminium alloy and carbon ... -
An experimental and numerical study of repairs on composite substrates with composite and aluminum doublers using riveted, bonded, and hybrid joints
Pitta, Siddharth; Roure Fernández, Francisco; Crespo Artiaga, Daniel; Rojas Gregorio, José Ignacio (Multidisciplinary Digital Publishing Institute (MDPI), 2019-09-14)
Article
Accés obertIn this work, experimental and numerical analyses of repairs on carbon fiber reinforced epoxy (CFRE) substrates, with CFRE and aluminum alloy doublers typical of aircraft structures, are presented. The substrates have a ... -
Comparison of fatigue crack growth of riveted and bonded aircraft lap joints made of Aluminium alloy 2024-T3 substrates – A numerical study
Pitta, Siddharth; Rojas Gregorio, José Ignacio; Crespo Artiaga, Daniel (Institute of Physics (IOP), 2017)
Text en actes de congrés
Accés obertAircraft lap joints play an important role in minimizing the operational cost of airlines. Hence, airlines pay more attention to these technologies to improve efficiency. Namely, a major time consuming and costly process ... -
Comparison of the performance of aircraft repair patches consisting of riveted lap joints on aluminium and composite substrates
Pitta, Siddharth; Rojas Gregorio, José Ignacio; Crespo Artiaga, Daniel (2017)
Comunicació de congrés
Accés restringit per política de l'editorialOne of the major contributions to aircraft operational costs corresponds to maintenance. This is a time consuming and expensive process, but necessary, for instance, to detect early formation of cracks, monitoring crack ... -
Comparison of the response of different configurations of aircraft repair patches under static and dynamic loading
Pitta, Siddharth (Universitat Politècnica de Catalunya, 2020-07-10)
Tesi
Accés obertIn the modern era of transportation, air travel has gained a huge pace and still kept increasing. The global demand for air transport is increasing at a rate of 6%, because of population growth and ticket price reductions. ... -
Fatigue life analysis of un-repaired and repaired metallic substrate using FRANC2D
Pitta, Siddharth; Rojas Gregorio, José Ignacio; Crespo Artiaga, Daniel; Wahab, Magd Abdel (2018)
Comunicació de congrés
Accés restringit per política de l'editorialWe present numerical investigations on fatigue life analysis of un-re-paired and repaired metallic substrate. Most of the engineering structures fail due to fatigue under dynamic loading. While research is mostly focused ... -
Investigation on repairs of aircraft composite structures made with various joining techniques
Pitta, Siddharth; Roure Fernández, Francisco; Crespo Artiaga, Daniel; Rojas Gregorio, José Ignacio (2018)
Comunicació de congrés
Accés restringit per política de l'editorialIn the race for developing aircraft with lighter airframe, aiming at increasing aircraft payload and/or fuel efficiency, the shift from conventional metal structures to light-weight composite structures has attracted ... -
On the static strength of aluminium and carbon fibre aircraft lap joint repairs
Pitta, Siddharth; de la Mora Carles, Victor; Roure Fernández, Francisco; Crespo Artiaga, Daniel; Rojas Gregorio, José Ignacio (2018-10-01)
Article
Accés obertThe behaviour of various aircraft lap joint repair configurations is investigated experimentally and numerically under static loading. The lap joints consist of aluminium alloy (AA) 2024-T3 substrates repaired with twin ...
