To investigate nonlinear bending of the functionally graded (FGM) plates with complex shape and resting on elastic foundation a variational-structural method (RFM) is proposed. Mathematical statement boundary value problems plate carried out in framework classical geometrically theory. solve sequence linear obtained as result linearization original system equations by successive loadings Newton...
a constitutive model based on two–dimensional unstructured galerkin finite volume method (gfvm) is introduced and applied for analyzing nonlinear behavior of cracked concrete structures in equilibrium condition. the developed iterative solver treats concrete as an orthotropic nonlinear material and considers the softening and hardening behavior of concrete under compression and tension by using...
Analysis of a laminated composite beam under impact by a rigid particle is investigated. The importance of this project is to simulate the impact of objects on small scale aerial structures. The stresses are considered uni- axial bending with no torsion loading. The first order shear deformation theory is used to simulate the beam. After obtaining kinematic and potential energy for a laminated ...
In this work, analytical solutions are provided to the nonlinear equations arising in thermal and flow-induced vibration in fluid-conveying structures using Galerkin-differential transformation method with cosine aftertreatment technique. From the analysis, it was established that increase of the length and aspect ratio of the fluid-conveying structures result in decrease the nonlinear vibratio...
کاربرد روش gdq برای نخستین بار در خصوص تحلیل استاتیکی غیرخطی سازه های به شکل ورق قطاعی، با درنظر گرفتن تیوری تغییر شکل برشی مرتبه اول (fsdt) و ترم های غیرخطی از نوع فون- کارمن که تحت بارگذاری گسترده یکنواخت قرار دارد، نشان داده شده است. این مسیله برای ورق ایزوتروپیک، fgm و کامپوزیت بررسی شده است. پنج معادله تعادل حاکم بر ورق و پنج شرط مرزی در هر لبه سازه با استفاده از اصل حداقل انرژی پتانسیل بد...
