Abstract:

The crushing process, peak load and energy absorption property of carbon epoxy circular waved beams under quasi static loading are investigated experimentally in this paper. Three sets of waved beams with different sizes are tested under compressive loads to failure. Based on the experimental data, the energy absorbing mechanism of the composite waved beams is studied. The peak loads and energy absorbing property are analyzed quantitatively. And the size effect on the peak load and the energy absorbing property is discussed.

Key words: composite material, waved beams, energy absorption, peak load
