ABSTRACT
In this paper, the mechanical behavior of CFRP curved stiffened fuselage panels under high velocity transverse impact loading is studied numerically. For that purpose, Abaqus/Explicit is used to perform the numerical study. Firstly, a brief introduction to the topic and a literature review is made. Then, the numerical models are described in detail. Afterwards, the numerical results are presented firstly for five panels with stringers having five different cross-section shapes (T, I, J, C and Ω) with the objective of identifying which cross-section yields the panel most resistant to impact. Secondly, for the panel chosen, a parametric study is conducted considering the influence of the following parameters: (i) location of the impact (aligned or in-between stringers), (ii) angle of impact and (iii) dimension and (iv) shape of the projectile. Finally, the main conclusions of the work are put forward.
