This paper presents an experimental investigation
for determination of the elastic modulus from two different
experimental tests dynamic free vibration and static tension
test. The material has been used in the current research is
processed by friction stir processing (FSP) technique in
order to fabricating a surface composite beams from AA2024
wrought aluminum alloy with Al2O3 Nano particles. The
mechanical properties and young's modulusare investigated
through tension test results. Dynamic Characteristics are
calculated from resonant vibration analysis; as well, the
natural frequencies are used as the parameters of
determining elastic modulus. The comparison results found
a closed convergence between the two techniques.
