Bending and free vibration analysis of functionally graded plates using new eight-unknown shear deformation theory by finite-element method
Journal Title: International journal of advanced structural engineering - Year 2016, Vol 8, Issue 4
Abstract
In this paper, a new eight-unknown shear deformation theory is developed for bending and free vibration analysis of functionally graded plates by finite-element method. The theory based on full 12-unknown higher order shear deformation theory simultaneously satisfies zeros transverse stresses at top and bottom surfaces of FG plates. A four-node rectangular elementwith 16 degrees of freedomper node is used. Poisson’s ratios, Young’s moduli, and material densities vary continuously in thickness direction according to the volume fraction of constituents which is modeled as power-law functions. Results are verified with available results in the literature. Parametric studies are performed for different power-law indices, side-to-thickness ratios.

Seismic response of an elevated aqueduct considering hydrodynamic and soil-structure interactions
In conventional design of an elevated aqueduct, apart from considering the weight of water inside the channels, hydrodynamic forces are generally neglected. In a few special cases involving high seismic zones, hydrodynam...
