Post-failure Motion Of Beams Under Blast Loads
Author(s)
N. Jones & M. Alves
Abstract
The post-failure motion of a simply supported beam subject to a blast loading,
which causes failure at the supports, is investigated analytically. The theoretical
solution adopts a rigid, perfectly plastic idealisation and is exact in the sense that
it satisfies the requirement of the upper and lower bound theorems of dynamic
plasticity. Attention is focused on the motion of the beam after it fails and becomes
detached from the supports. Part of the energy remaining in the beam after failure
is responsible for changing the beam shape after severance, a feature investigated
here.
