Bogush M.V. Mechanical reliability evaluation for the sensing elements of piezoelectric sensors

The paper describes a mechanical availability evaluation method for a sensing element (SE) – a critical component of a piezoelectric sensor. The method is based on the analysis of a 3D model of the stress condition subject to the pressure affecting the SE and temperature changes. Such analysis improves the reliability of estimates under operation conditions.
