本文仅讨论区域应力场,在区域应力场研究中,其它手段为有限单元计算提供应力边界条件,而数值计算对区域应力场提供新的资料和证据。
In this paper, only the regional stress field is discussed. In the study of the regional stress field, other means provide the stress boundary conditions for the calculation of the finite element. Numerical calculation provides new data and evidences for the regional stress field.
