The structural response of thin-walled pipes subject to impact by hard missiles has been investigated experimentally for Nuclear Electric plc in the Horizontal Impact Facility (HIF) at Winfrith Technology Centre. The data from the tests have been used to validate the finite element code DYNA3D as a structural design and assessment tool.
The DYNA3D analyses accurately predict the global and local deformations of the pipes, and the induced strains near to, and distant from the site of impact.
