An Analytical Model of Circular Elastic Element of the Pressure Sensor with Radial Compression Integrated into the Model

摘要

A circular, hardly claimed isotropic elastic element is analyzed under the conditions of simultaneous effect of transverse mechanical loads and compressive mechanical stresses in the plane of this elastic element. An exact solution providing the distribution of strains is obtained. Some simplified equations defining the strains near the edge of the elastic element are obtained. Additionally, the similar equations are provided for the point of center of this element. All obtained analytical equations are practically convenient. An increasing of sensitivity of this elastic element after simultaneous application of the transverse load and compressive planar mechanical stresses is shown in this paper as well.
