Incremental formulation for finite strain and finite rotation of continuum mechanics
Due to some confusions existing in the current coordinate description of large rotation and large strain of continuum mechanics, there are always undiscernible mistakes in the formulation of the finite element method for large displacement problems. The object of this paper is to scrutinize some basic theoretical points of view in continuum mechanics of finite deformation by the author's geometrical field theory [Acta Mech. Sin. 1979, 107-117 (1979; Zbl 0444.73029)], and to formulate fundamental equations of incremental displacement for the finite element method by the energy principle of power type.
