A 2D field-consistent rational Bezier beam element for large displacement analysis
Name: Duy, Vo
keyword:
Beam element
Abstract:
Large displacement analysis of beams has been investigated extensively during the past decades. Many beam element formulations have been studied and proposed for this purpose. The efficiency is gradually improved in such a way that later beam elements are capable of giving better accuracies by using smaller numbers of degrees of freedom. This subsequently results in saving of time and effort needed in large displacement analysis of beams. In this study, a new 2D field-consistent Bézier beam element for large displacement analysis is proposed. The interpolation functions of the proposed element are constructed by using a rational Bézier curve to represent the geometry of the element. The interpolation functions are constructed in such a way that the consistency among the unknown fields is obtained. The formulation of the proposed element is based on the total Lagrangian description. A rational Bézier curve is used instead of polynomials in order that complex configurations of beams can be accurately reproduced using small numbers of elements. The employed field-consistent interpolations increase the performance of the element and remove the problem of shear locking. The proposed beam element is tested by several benchmark problems and the results are found to be satisfactory.
