this paper may be regarded as a new numerical method for the analysis of triangular thin plates using the natural area coordinates. previous studies on the solution of triangular plates with different boundary conditions are mostly based on the rayleigh-ritz principle which is performed in the cartesian coordinates. consequently, manipulation of the geometry and numerical calculation of the int...

In this research paper, the formulation of a new three-dimensional sector element based on the strain approach is presented for plate bending problems and linear static analysis of circular structures. The proposed element has the three essential external degrees of freedom (Ur, Vθ and W) at each of the eight corner nodes. The displaceme...

Current design and analysis methods of helical springs are significantly confined to a simple linear domain. The traditional spring formula is only effective for analyzing with geometric properties like constant coil diameter, unchanged pitch no contact. An advanced analytical model proposed in this study address the non-linear effects variable contact that exist arbitrary shapes. It aims expan...

In this work, a finite element model to perform the thermal–structural analysis of beams made functionally graded material (FGM) is presented. The formulation based on third-order shear deformation theory. constituents FGM are considered vary only in thickness direction, and effective properties evaluated by means rule mixtures. volume distribution top constituent modeled using power law form. ...

the purpose of this study is to determine the effect of vierendeel panel width and vertical truss spacing ratio in an inelastic behavior of the stf system due to earthquake loads. the stf system is applied to a six-storey building that serves as apartments [2]. the stf system is used in the building in the transverse direction (n-s direction), while in the longitudinal direction (w-e direction)...
