Abstract (EN): The human ear is a complex biomechanical system and is divided in three parts: external, middle and inner ear. The middle ear is formed by three ossicles (malleus, incus and stapes), ligaments and muscles that amplify the sound waves sending them to the inner ear. In this work, a finite element modelling of the middle ear was made. For this purpose, we show an approximate 3D solid model of the ossicles and eardrum, based in imagiology. Ligaments and tendons with hyperelastic behaviour were include, using the Yeoh model. With ABAQUS program, the discretization of these components was done. The connection between ossicles was made using contact formulation. With this model it is possible to do static and dynamic studies for better understand the ear behaviour and posteriorly to obtain improved solutions for hearing problems.
