摘要：
In this paper, we propose high-order interface-penalty finite element methods for elasticity interface problems in three dimensions. Optimal error estimates are proven in energy norms for interface-penalty finite element methods. The error estimates are independent of the cut configurations. A series of three-dimensional numerical results confirm the efficiency of the proposed methods.
