摘要: 本文从Dluzewski提出的以欧拉角为角坐标的建议和推导出的Cauchs型动力学方程组出发,又引进若干有关变形几何学和动力学的新定义并推导出有限变形极性弹性介质的Boussinesq型、Kirchhoff型、Signorini型和Новожилов型动力学方程组.Abstract: In the present paper,some additional new defmitions on the kinematics and dynamics are introduced,and the dynamical equations of Boussinesq type,Kirchhoff type,Signorini type and Nowzilov type for finite deformable polar elaslic media are systematically derived from the consideration of Euler angles as angular coordinated and the dynamical equations of Cauchy type presented by Dluzewski.
