[ 1 ] - Non-linear Static Modeling of Moderately Thick Functionally Graded Plate Using Dynamic Relaxation Method
In this paper, nonlinear static analysis of moderately thick plate made of functionally graded materials subjected to mechanical transverse loading is carried out using dynamic relaxation method. Mindlin first order shear deformation theory is employed to consider thick plate. Discretized equations are extracted for geometrically nonlinear behavior analysis.Loading Conditions and boundary condi...
[ 2 ] - Nonlinear Thermo-Mechanical Behaviour Analysis of Activated Composites With Shape Memory Alloy Fibres
General thermo-mechanical behavior of composites reinforced by shape memory alloy fibers is predicted using a three-dimensional analytical micromechanical method to consider the effect of fibers activation. Composite due to the micromechanical method can be exposed to general normal and shear mechanical and thermal loading which cause to activate the shape memory alloy fibers within polymeric m...

[ 4 ] - Dynamic Analysis of Offshore Wind Turbine Towers with Fixed Monopile Platform Using the Transfer Matrix Method
In this paper, an analytical method for vibrations analysis of offshore wind turbine towers with fixed monopile platform is presented. For this purpose, various and the most general models including CS, DS and AF models are used for modeling of wind turbine foundation and axial force is modeled as a variable force as well. The required equations for determination of wind turbine tower response ...
[ 5 ] - تحلیل ارتعاشات آزاد برج توربین بادی فراساحلی با سکوی ثابت تک شمع
Finite elements method can considerably increases the computational works of free vibration analysis of offshore wind turbine with fixed monopile platform depending on the modeling type of foundation,. In this paper, transfer matrix method is used to reduce computational works and increase the speed of analysis instead of the finite elements method. For this purpose, the wind turbine foundation...
