“…Joldes et al [4] and Taylor et al [5] achieve real-time computations of soft tissue deformations for nonlinear FEM using GPUs; however, they do not describe how they compute stiffness matrices; thus, we cannot implement their methods and compare them with our proposed method. Cerrolaza and Osorio describe a simple and efficient method to reduce the integration time of nonlinear FEM for dynamic problems using hexahedral 8-noded finite elements [6]. We compare our stiffness matrix calculations with Pedersen's method [3] to measure performance and verify correctness.…”

“…São produtos de uma extensa linha de estudo que, na segunda metade da década de 90, avaliou-se ser composta por mais de 56000 artigos, 380 livros e 400 anais de congressos [148]. É possível afirmar que o Método dos Elementos Finitos aplicado à análise de estruturas sólidas está em constante evolução, com o desenvolvimento de formulações de elementos mais aperfeiçoadas [79,86,89,105,135,182,197,203,232,246], novos modelos de materiais [14,67,168], propostas de algoritmos numéricos [171,200,251], otimizações [44,53,181], notas de aplicação [3,206], entre outros tópicos.…”
