The meshless element-free Galerkin method was generalized and an algorithm was developed for 3D dynamic modeling of deformable bodies in real time. The efficacy of the algorithm was investigated in a 3D linear viscoelastic model of human spleen subjected to a time-varying compressive force exerted by a surgical grasper. The model remained stable in spite of the considerably large deformations occurred. There was a good agreement between the results and those of an equivalent finite element model. The computational cost, however, was much lower, enabling the proposed algorithm to be effectively used in real-time applications.
对无网格无单元伽辽金方法进行了推广，并开发了一种算法用于实时动态模拟可变形体的三维模型。在一个三维线性粘弹性人体脾脏模型中，研究了该算法的有效性，该模型受到手术抓钳施加的随时间变化的压缩力作用。尽管发生了相当大的变形，该模型仍保持稳定。结果与等效有限元模型的结果吻合良好。然而，计算成本要低得多，这使得所提出的算法能够有效地用于实时应用。
