Apresentamos um modelo computacional para estruturas flexíveis de geometria arbitrária no espaço tridimensional com a cinemática governada pela teoria de barras com flexão, cisalhamento, torção e efeito de membrana. Um método misto de Petrov-Galerkin é usado para construir uma aproximação estabilizada de elementos finitos. Estimativas de erro indicando taxas de convergência bem como resultados numéricos comprovando tais taxas são apresentados.References
