Abstract: | The paper summarises recent progress on materials modelling and numerical simulation of soft body impact damage in fibre reinforced
composite aircraft structures. The work is based on the application of finite element (FE) analysis codes to simulate damage
in composite shell structures under impact loads. Composites ply damage models and interply delamination models have been
developed and implemented in commercial explicit FE codes. Models are discussed for predicting impact loads on aircraft structures
arising from deformable soft bodies such as gelatine (synthetic bird) and ice (hailstone). The composites failure models and
code developments are briefly summarised and applied in the paper to numerical simulation of synthetic bird impact on idealised
composite aircraft structures. |
