Axial crushing of aluminum extrusions filled with PET foam and GFRP. An experimental investigation
Costas, Miguel; Morin, David; Langseth, Magnus; Romera, Luis Esteban; Díaz, Jacobo M. (Journal article, 2016)This research work investigated the axial crushing behavior of a circular aluminum extrusion in alloy AA6063-T5 internally reinforced with a glass–fiber structure and filled with polymeric foam. The components were ... -
Energy Absorption of Aluminium Extrusions Filled with Cellular Materials Under Axial Crushing: Study of the Interaction Effect
Paz, Javier; Costas, Miguel; Delgado, Jordi; Romera, Luis Esteban; Diaz, Jacobo (Peer reviewed; Journal article, 2020)This investigation focuses on the interaction effect during the quasi-static axial crushing of circular and square thin-walled aluminium extrusions filled with polymeric foam or cork. The increment in the absorbed energy ... -
On the importance of tunica intima in the aging aorta: a three-layered in silico model for computing wall stresses in abdominal aortic aneurysms
de Lucio, Mario; Fernandez, Marcos; Diaz, Jacobo; Romera, Luis Esteban; Álvarez Marcos, Francisco (Peer reviewed; Journal article, 2020)Layer-specific experimental data for human aortic tissue suggest that, in aged arteries and arteries with non-atherosclerotic intimal thickening, the innermost layer of the aorta increases significantly its stiffness and ... -
Static crushing of aluminium tubes filled with PET foam and a GFRP skeleton. Numerical modelling and multiobjective optimization.
Costas, Miguel; Morin, David; Langseth, Magnus; Díaz, Jacobo M.; Romera, Luis Esteban (Journal article; Peer reviewed, 2017)This investigation focuses on the multiobjective optimization of a crash box subjected to static loading by using a validated numerical model and an analytical approach. The crash box is made with a unique combination of ...
