Study of the mechanical properties of the avian middle ear by optical interferometry and finite element modeling
Introduction In all mammals, the middle ear is made up of an eardrum and three hearing bones we call ossicles. These ossicles function as an impedance match between the air in the outer ear and the fluids in the cochlea of the inner ear. Acoustic energy is absorbed by the eardrum, converting it into mechanical vibrations, and the ossicles transports these vibrations in a very efficient way towa...
متن کاملEARDRUM DISPLACEMENT FOLLOWING STAPEDIUS MUSCLE CONTRACTION by
Simultaneous monitoring in human subjects on the same ear of eardrum displacement by tympanomanometry, and acoustical impedance by the Madsen bridge, provided information concerning contraction of the stapedius muscle and its effect on eardrum displacement. Extensive control procedures were employed to elicit only the stapedius reflex: lower intensity auditory stimulation, electrocutaneous stim...
متن کاملStatic and Pseudo Static Study of Stress and Displacement of Earth-Fill Dam Using Layered and Single-Layer Models
Earth-fill dams stability in steady state seepage condition is very important, especially during earthquakes. Numerical software analyses require accurate and realistic modeling of construction stages. Since earth-fill dams are constructed in different layers, so these conditions should be considered in software modeling to achieve a reasonable design. In this study, an earth-fill dam is modele...
متن کاملStrength Prediction in CFRP Woven Laminate Bolted Single-Lap Joints under Quasi-static Loading using XFEM
This paper is concerned with modelling damage and fracture in woven fabric CFRP single-lap bolted joints that fail by net-tension. The approach is based on the assumption that damage (matrix cracking, delamination and fibre tow fracture) initiates and propagates from the hole in a self-similar fashion. A traction-separation law (based on physically meaningful material parameters) is implemented...
متن کاملA single camera roentgen stereophotogrammetry method for static displacement analysis.
A new method to quantify motion or deformation of bony structures has been developed, since quantification is often difficult due to overlaying tissue, and the currently used roentgen stereophotogrammetry method requires significant investment. In our method, a single stationary roentgen source is used, as opposed to the usual two, which, in combination with a fixed radiogram cassette holder, f...
