1.本文首先討論在一种可能的一般意义下发展的可变形体理論的对象和假設,着重解决与各向异性、非綫性、塑性及非均匀性有关的問題。也指出了与时間有关的(流变的)現象。 同时,文中說明了这些假設使理論上的考虑和結果与在土木工程中所用的結构材料的真实性貭接近了。从这些一般假設看来,“古典的”,即以綫性虎克定律和小变形假設为基础的弹性力学只是理想化的特殊情况之一。
1. This paper begins with a discussion of the objects and assumptions of deformable body theory, developed in a possible general sense, focusing on problems related to anisotropy, nonlinearity, plasticity, and inhomogeneity. Also pointed out that time-related (rheological) phenomenon. At the same time, the paper states that these assumptions bring the theoretical considerations and results closer to the authenticity of the structural materials used in civil engineering. From these general hypotheses, “classical” elasticity, which is based on the linear Hooke’s law and the hypothesis of small deformation, is but one of the special cases of idealization.
