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...
We present isogeometric shape optimization for shell structures applying sensitivity weighting and semi-analytical analysis. We use a rotation-free shell formulation and all involved geometry models, i.e., initial design, analysis model, optimization model, and final design use the same geometric basis, in particular NURBS. A sensitivity weighting scheme is presented which eliminates certain ef...
In this study, Homotopy analysis method is employed for nonlinear vibrational analysis of marine riser subjected to variable axial loads. Mid-plane stretching effect has been considered in the model. Galerkin's decomposition technique is used to convert the Partial differential equation of the motion to nonlinear ordinary differential equation. Homotopy analysis method (HAM) is applied to find ...
