Influence of the size and depth of a circumferential notch on the impact behavior of streetlights. A passive-safety concept
(Elsevier, 2015-07)
Impact tests on weakened streetlights were carried out using a high energy pendulum. The weakening mechanism consists of a circumferential notch at the base of the streetlight. The objective is twofold: firstly to reduce ...

Experimental study of the size effect on transverse cracking in cross-ply laminates and comparison with the main theoretical models
(Elsevier, 2019-01)
Transverse cracking of off-axis plies is typically the first step of some failure mechanisms in long fiber reinforced laminated composites. It is well known that the off-axis ply thickness affects strongly the strain level ...
