1. I N T R O D U C T I O N In recent years, there has been a marked interest in the so-called meshless methods. The possibility of obtaining approximate solutions to various problems of mechanics (of engineering, in general) without the need for a mesh is quite appealing, in particular due to the reduction in time consumption and the time taken in preparing(More)
Abstract. This paper presents a meshless implementation for the dual analysis of 2D linear elasticity problems. The derivation of the governing system of equations for the discretized equilibrated model is detailed. Crucial implementation issues of the equilibrated algorithm are described. It presents the inf-sup condition for particular cases of essential(More)
In this work a hybrid-Trefftz formulation and a meshless approach based on the use of radial basis functions (RBF) are applied to the analysis of reinforced concrete beams. Resorting to the Mazars model, the concrete is represented by an elastic medium with progressive damage. In the hybrid-Trefftz formulation a stress field that satisfies a priori the(More)
