Abstract
Procedures are developed to facilitate laboratory investigation of
the effects of short-duration transverse impact loading on simply
supported beams. The particular beam investigated was aluminum, with
constant rectangular cross-section. Six loading conditions were examined,
consisting of a central impact from three heights for each of
two spherical masses. Theoretical analysis was made of the frequency
and deflection characteristics for ten equally spaced locations on the
beam, under the assumption of Euler's beam theory. Experimental data
were compared with theoretical values to give an indication of the effectiveness
of the theoretical system in representing the physical
system. It was concluded that the theory gives a good representation
of the physical system, especially with respect to the frequency characteristics.
