Abstract
Geometric nonlinearities are included in an existing finite-element model of the cat eardrum. The model is used to simulate the response of the eardrum to large static pressures after manubrial fixation. The nonlinear model agrees with the experimental observation that the middle ear is linear up to about 90 Pa. The response of the model becomes significantly nonlinear at higher pressures which has also been found in recent experimental work on the eardrum
