A numerical model based on finite elements was developed. Results obtained from numerical simulations showed coupled influence of temperature combined with torque level on the joint Description: 15th International Conference on Composite Structures (ICCS/15), University of Porto, Porto, Portugal, 15-17 June 2009 2009-05-31T22:00:00Z http://hdl.handle.net/10016/14575 Title: Modelling of composite sandwich structures with honeycomb core subjected to high velocity impact Author(s): Buitrago, Brenda L.; Santiuste, Carlos; Sánchez-Sáez, Sonia; Barbero, Enrique; Navarro, Carlos Abstract: In this study the behaviour of composite sandwich panels with aluminium honeycomb core subjected to high velocity impact was analysed by a numerical model which was validated by experimental tests.

Results are compared with those obtained when no static loads are applied to the specimens. Two magnitudes were measured from the tests: the residual velocity of the impacting projectile and the extension of the damage area in the laminate. Description: ICCE 12.

Two kinds of lightweight materials were considered: aluminium alloy 7075 and quasi-isotropic glass fibre-reinforced vinylester resin. The residual velocity, the ballistic limit and, in the case of the composite material, the delaminated area, were measured in each test. Unstable cracks, that generate the catastrophic failure of the panel, were observed in the case of the aluminium at pre-stressed load levels lower than those inducing material yielding.
