The vibration of structures immersed in water has been studied by Lamb and others. The influence of thermal stresses on the vibration characteristics of plates has been investigated and reported by several researchers. The work reported here deals with the determination of natural frequencies of plates immersed in water and subjected to six types of temperature distributions. The analysis is based on finite element method. A comment on thermal buckling of plates immersed in water is also reported. © 1985.

Influence of fluid added mass on the vibration characteristics of plates under various boundary conditions

Prismatic shells find wide application in mechanical, civil and aeronautical engineering. The object of this paper is to propose a method of analysing such shells having different internal ribbing for their torsional vibrations. The governing equations of motion are derived by using a finite difference method and solved by the simultaneous iteration technique. The accuracy of the method is ascertained by comparing the results for some wellknown boundary conditions with the results obtained by classical methods. Shells of square cross-section and rectangular shells of variable and constant cross-section have been analysed. The effects of introduction of diaphragms on the eignefrequencies have been analysed. The effects of variations in shell thickness and length on the dynamic behaviour also have been studied. © 1975 Academic Press Inc. (London) Limited.
