This paper describes pushing operation modeling of brain tissue for the brain surgery simulator. To ensure operative field, this operation is first aimed at resection surgery of brain tumor. Using a brain spatula, cerebral sulcus and two cerebral hemispheres are pushed aside by brain surgeons. Therefore, modeling of forces and deformations occured by contact is required. Those forces have three components, that is the resistance force, the friction force and the viscosity resistance. And deformations is calculated by geometrical relation between models. In the simulation experiment, the availability of this operation modeling is also confirmed.
