本文讨论了承受高速动载荷厚板结构的力学量分布规律、厚壁因素效应、厚跨比影响范围、结构的动力反应以及厚薄界限,剪弯界限等一系列力学形态,重点指出其和一般薄板分析的差别.研究结果对于其它厚壁结构如深梁、厚框、厚拱、厚壳等,也可作类似分析.厚板结构的力学形态(一)位移、应力沿厚度方向分布规律1.垂直挠度 w 沿厚度分布基本上仍保持常
This paper discusses the mechanical distribution of thick plate structure subjected to high-speed dynamic load, the effect of thick wall factor, the range of influence of the thickness and span ratio, the dynamic response of the structure, and the thickness and shear boundaries, and a series of mechanical forms, highlighting the general mechanical properties of the plate. Analysis of the differences. The results of the study for other thick-walled structures such as deep beams, thick frames, thick arches, thick shells, etc., can also be similarly analyzed. The mechanical form of the thick plate structure (1) Displacement, stress distribution along the thickness direction 1. The vertical deflection w remains substantially constant along the thickness distribution
