Several numerical solution techniques for nonlinear eardrum-type oscillations

Three numerical solution techniques for nonlinear eardrum-type oscillations with an even function in the restoring force are studied. The first suggested technique is named the target function technique. In the technique, the second zeros of the target function is the circular frequency of motion. The second suggested technique is named the multiple-parameter technique, and the involved parameters are evaluated from the governing equation, the initial conditions, and properties of motion. The third suggested technique is named the direct integration technique. All techniques depend on the computer computation significantly and provide very accurate numerical results. Finally, numerical examples are given. (c) 2006 Elsevier Ltd. All rights reserved.
