【摘要】 本文以各种理论的基本假设为出发点 ,详细讨论并分析了三维弹性理论、平面问题、经典薄板理论、厚壁结构理论之间的过渡与联系 ,即经典理论实际上是三维弹性理论在某些特殊尺寸形状物体范围内的简化 ,而厚壁结构理论则是三维弹性理论与经典理论之间的过渡与联系。同时说明了基本假设对各种理论建立的重要性。更多还原

【Abstract】 Taking the basic hypothesis of various theories as the starting point, the paper discusses and analyzes in detail the transitions and relations among 3-dimension elastic theory, plane question, classical thin plate theory and thick-walled construction theory, i.e., classical theory is the simplicity of 3-dimension elastic theory in the extent of some particular form bodies, and thick-walled construction theory is the transition and relation of 3-dimension elastic theory and classical theory. At the same time, the importance of the basic hypothesis for the establishment of all theories is stated.更多还原
