Wave Propagation,the Dynamics of Elastic Structures and Stability,and Neutron Transport.

摘要

A total of nine investigators completed 32 research projects yielding 22 publications, 10 accepted or submitted, and 5 in preparation. Subject areas were structural analysis (12), wave propagation (13), fluid dynamics (5), and transport theory (5). Topics included higher order buckling in the presence of imperfections, dynamic instability, composite material, wave propagation through nonlinear and random media, vortex motion in fluids, the small mean free path approximation to the transport equations, etc. Asymptotic, perturbation and bifurcation techniques predominated.
