Nonlinear Constitutive Relation

Based on the normal CT scan image of human right ear, numerical model has been established combined with self-compiling program. The nonlinear constitutive relation of real middle ear material has been included, and sound - solid and liquid - solid coupling method have been adopted to simulate the sound transmission process from external auditory canal to tympanic membrane, auditory ossicle chain, and eventually to the inner ear. Frequency response and sound transmission behavior has been obtained, and numerical calculation results have been verified by comparing the calculation results with the experimental data. The amplitude, vibration velocity, and stress distribution of middle ear have been analyzed by the model, and the most easy damage part of the tympanic membrane and ossicular chains owing to stress concentration have been obtained in sound transmission of middle ear, which exposes the inner relationship between mechanical behavior of middle ear and pathological changes.
