The plane two-node curved beam finite element with six degrees of freedom is considered. Knowing the set of 18 exact shape functions their approximation is derived using the expansion of the trigonometric functions in the power series. Unlike the ones commonly used in the FEM analysis the functions
The flexural stiffness for a horizontally curved beam element is developed for nodal parameters wi, (a wlds),, pi, (@/as),, (a'p/ds'),, (d3p/as3), by assuming a cubic displacement function for vertical deflection w, and a seventh order polynomial function for the angle of twist /3, along the length
Curved beam finite elements with shear deformation have required the use of reduced integration to provide improved results for thin beams and arches due to the presence of a spurious shear strain mode. It has been found that the spurious shear strain mode results from an inconsistency in the displa
