The Effects Of Nonlinear Damping On The Large Deflection Response Of Structures Subjected To Random Excitation, Chunchu Bhavani Prasad
Mechanical & Aerospace Engineering Theses & Dissertations
Effects of both nonlinear damping and large deflection stiffness are included in the theoretical analysis in an attempt to explain the experimental phenomena of aircraft panels excited at high sound pressure levels; that is the broadening of the strain response peak and the increase in modal frequency. Beams and symmetrically laminated plates subjected to acoustic excitation are considered in the analyses. The excitations are ergodic and Gaussian with zero mean. A polynomial containing both linear and nonlinear damping terms is considered as a damping model. Galerkin's method is used to derive modal equations. Direct equivalent linearization is used to solve …

Man observes many phenomena occurring in nature which he can use to his benefit. He observes how physical quantities vary as a function of their environment in order to predict how these variations will affect a system he wishes to design. For this purpose, he must establish a model that is representative of the relation between those physical quantities and certain environments to which they are subjected.
