摘要：
We introduce in this Note a new family of mixed finite elements for the linear elastodynamic problem. We present the construction of the lowest order element in the 2D case together with the dispersion analysis for an isotropic homogeneous medium. This construction can be extended to higher orders as well as to the 3D case.
