DESCRIPTION:Miguel Herraez\, LMAF\, EPFL\nAbstract Composites are define
 d as heterogeneous materials made from two or more constituents with signi
 ficantly different properties. For instance\, fiber-reinforced polymers a
 re made of strong and stiff fibers embedded in a polymer matrix\, what mak
 es them ideal candidates in structural lightweight applications. One of th
 e most common architectures in which these materials are found in structur
 es is as stacks of composite plies\, also known as laminates. Despite thei
 r excellent properties\, the heterogeneity and anisotropy shown by this ki
 nd of material are responsible for the complex fracture and failure modes 
 that they exhibit. Delamination is a very common damage mode exhibited by
  laminated composites and has been extensively studied in unidirectional l
 aminates. Nevertheless\, for the case of general ply-stacking configuratio
 ns\, like multidirectional laminates\, their behaviour is not fully unders
 tood\, since different damage mechanisms participate in the fracture proce
 ss. An experimental campaign was carried out to evaluate the mechanical re
 sponse of different angle-ply laminates under mode I and mode II fracture.
  In this work\, we will show the experimental results and modelling effort
 s at different scales devoted to analyse and understand the different dama
 ge mechanisms observed and their interaction during the fracture process (
 e.g.\, delamination\, matrix cracking\, crack migration...).
