ABSTRACT
This paper investigates the properties of a recently proposed
physical model of nonlinear tension modulation effects in a
struck circular membrane. The model simulates dynamic
variations of tension (and consequently of partial frequen-
cies) due to membrane stretching during oscillation, and
is based on a more general theory of geometric nonlinear-
