Abstract
En 中文
This paper presents a new algorithm to identify the occurrence of impact (contact) among structures. Structures are modeled here by finite elements and the resulting formulation is employed to solve two-dimensional frame impact problems by the Lagrange Multiplier technique. The proposed algorithm is based on potential theory, largely employed in various fields of physics. The potential theory is used together with integral equations making possible to compare relative positions among nodes of different structures involved in a collision process. The present technique may be used to model the contact prevision among two or three-dimensional structures or between structures and rigid obstacles. In order to show the applicability of the proposed technique, numerical answers for 2D problems are compared with both analytical solutions and numerical results given by other authors.
