Abstract AR
يتناول هذا البحث الدراسة النظرية للاهتزازات الحرة للقشريات نحيفة الجدران البيضاوية الشكل المتطاولة المتناظرة المحور المتشابهة الخواص في جميع الاتجاهات, و قد أجري التحليل النظري بطريقة رايلي - رتز.
إن هذه الطريقة بالرغم من كونها تقريبية, و لكن بالإمكان الاعتماد عليها لحساب الذبذبة الطبيعية لهذه القشريات. من خلال النتائج وجد أن تلك الطريقة أعطت نتائج جيدة للترددات الطبيعية للقشرة البيضاوية المتناظرة المحور لكل قيم اللامركزية.
Abstract EN
In this paper a detailed study of the theory of free axisymmetric vibration of thin isotropic prolate spheroidal shells is presented.
The analysis is performed according to Rayleigh–Ritz method.
This method as well as an approximate modeling technique were attempted to estimate the natural frequencies for the shell.
This technique is based on considering the prolate spheroidal as a continuous system constructed from two spherical shell elements matched at the continuous boundaries.
Through out the obtained results it is found that this method predicted fairly well the natural frequencies of a prolate spheroidal shell for all values of eccentricities.
