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.
