    Abstract

    The static and dynamic response of a cylindrical/spherical containment to a Boeing 720 impact is computed using 3 different linear elastic computer codes: FINEL, SAP and STARDYNE. Stress and displacement fields are shown together
    with time histories for a point in the impact zone. The main conclusions from this study are:
    - In this case the maximum dynamic load factors for stress and displacements
    were close to 1, but a static analysis alone is not fully sufficient.
    - More realistic load time histories should be considered.
    - The main effects seem to be local. The present study does not indicate general
    collapse from elastic stresses alone.
    - Further study of material properties at high strain rates is needed.
