Adaptive nonlinear elastic FEM for realistic prediction of soft tissue in craniofacial surgery simulations

摘要: In craniofacial surgery simulations, the realistic prediction of a patient's postoperative appearance is utmost importance. Due to complexity biomechanical behavior soft tissue simplified models such as widespread linear elastic are usually applied. However, large deformations often occurring in can't be accurately modeled via approach, since it generally limited by assumption small deformations. this paper, we present an adaptive nonlinear approach based on finite element discretization 3D model, which free linearization limitations and yields more results simulations facial deformation.
