RESUMO
AbstractThis paper presents an extension of BATTINI´s formulation to two-dimensional analysis of nonlinear dynamical problems. The main interest of the co-rotational approach is to separate rigid body motions from pure deformations at the local element level through co-rotated framework. Employing co-rotated framework to derive both internal and inertial terms is the objective of the formulation presented in this study. Numerical examples are presented to illustrate the ability of the proposed co-rotational formulation.
