Abstract
The objective of this research program is to study the dynamics of a composite driveshaft before and after ballistic damage is incurred. Driveshafts are tested under static and dynamic loads to obtain material, mechanical, and vibrational characteristics. In the dynamic tests, driveshafts with and without ballistic damage are observed to determine the critical speeds. The torsional modulus, the longitudinal modulus, and Poisson's ratio are determined from the static tests. Computational models are used to perform parametric studies and to complement the experimental program. Numerical simulations incorporate both beam and shell theory into the analysis. Additionally, non-destructive evaluation (NDE) was used to help determine the extent of the damage caused by the projectile.
