The Influence of Tensile Forces on the Deflection of Circular Diaphragms in Pressure Sensors
نویسنده
چکیده
It 1s known that the deflection of a diaphragm 1s determmed by two mechamsms, bendmg moments or bendmg stress and tensile forces or membrane stress Usually the influence of tensile forces 1s not taken mto account when calculating the mechamcal properties of thm diaphragms Hence the mathematical descrlptlon thus obtamed will only be valid if the deflection of the diaphragm is small compared with its thickness and if lateral stress is absent In this paper we will consider uniformly loaded circular diaphragms, which are assumed to be lsotroplc, and present the results of a study on the influence of bendmg stress and tensile stress, which together determine the diaphragm deflectlon Startmg from theoretical conslderatlons, a sunulatlon program 1s developed of which several results are presented and discussed
