in this research three-dimensional free vibration analysis of functionally graded circular plate with various boundary conditions is achieved. a semi-analytical method, which makes use of the state space method and the one-dimensional differential quadrature method, is used to obtain the vibration frequencies and dynamic responses of circular plates. numerical results are given to demonstrate t...

Original scientific paper Finite difference procedures for flux determination are not well suited for application to field results obtained from finite element calculations. A novel method for flux calculation has been derived. This method is based on the weak formulation and is suitable for use with finite elements. A matrix formulation for local and global application to finite element formul...

in order to investigate the structural behaviour of persian brick masonry domes, three types of semi-circular, (drop, ordinary and raised) four-centred and (drop, ordinary and raised) pointed domes have been studied. the three-dimensional non-linear finite element method using the ansys code has been used for analysis. domes with different thicknesses and spans have been subjected to monotonic ...
