AbstractWhen multiple trapezoidal four-node plane elements are used to model slender beams, it is found that the transverse bending stress/strain mode which should physically vanish is most detrimental to the element accuracy and leads to a deficiency which is sometimes known as 'trapezoidal locking'. In this paper, immunity of four-node five-beta hybrid elements to 'trapezoidal locking' in practical analyses is obtained by a simple selective scaling procedure that judiciously reduces the stiffness arising from the two bending stress/ strain modes in the elements.
