Abstract (EN): A formulation for a quadrilateral finite element with an embedded discontinuity, designed for large displacements, is presented. Lagrange multipliers are used to impose the condition that the embedded discontinuity is not activated before crack initiation. Additional degrees of freedom are incorporated in the element, including rotations, which permit the representation of the two states of the crack. A strain enhancement technique is utilised to improve the performance of the element in bending. Some numerical examples are used to illustrate the robustness of the proposed solutions.
