SCALING EFFECTS IN THE STATIC AND DYNAMIC RESPONSE OF GRAPHITE-EPOXY BEAM-COLUMNS ABSTRACT Scale model technology represents one method of investigating the behavior of advanced, weight-efficient composite structures un-der a variety of loading conditions.

Testing of scale models can provide a cost effective alternative to destructive testing of. Dec 01,  · Experiments were performed on graphite-epoxy composite specimens having different laminate stacking sequences and a range of scaled sizes.

From the experiments it was deduced that the elastic response of scaled composite specimens was independent of size.
