A new class of mechanical response characteristics in composite materials is reported. These characteristics were found to come about because of a nonlinear dependence of the fatigue response of biasply boron-aluminum and boron-epoxy flawed plate specimens on the frequency of load (or strain) oscillation. This nonlinear frequency effect was found to alter such properties as fatigue strength, stiffness, residual strength, and energy dissipation by as much as an order of magnitude. Several conceptual interpretations are developed and compared with data correlations.
