“…The implementation of this method in ANSYS consists in adding new variables to the system, instead of adding the stiffness of the contact elements directly into the global stiffness matrix [15]. The advantage of this approach is the possibility to enforce a zero penetration condition since the normal contact stiffness is not part of the method [19]. However, the additional Lagrange Multipliers require more iterations for the analysis to converge compared to other contact algorithms.…”

“…A implementação deste método no ANSYS consiste em se adicionar os multiplicadores de Lagrange ao sistema, ao invés de adicionar os elementos de contato diretamente na matriz de rigidez global [2,4]. A vantagem desta formulação é a possibilidade teórica de se obter a condição de penetração zero sem lidar com a rigidez de contato [21]. Mas devido ao acréscimo de variáveis, a solução é geralmente obtida com um número maior de iterações.…”
