| 摘 要： | 本文主要论述双传感器二序列图象组合技术方案的识别和检测理论.文中提出用张角(θ)、斜角(Φ)和摆角(?)描述刚体平面在三个坐标平面内的旋转,并且建立了θ、Φ和(?)与旋转矩阵R 的函数关系.还提出了充分地确定变换矩阵A,充分地和唯一地确定瞬间的三维运动参数和几何参数(无待定标量因子),以及恢复物体空间结构等有关的学术观点,给出了由此导出的数学模型.

| Abstract: | This paper introduces a study of the engineering method for elastic-plastic frac-ture analysis of welded joints.A conclusion has been drawn from the results of the re- search that the EPRI method for elastic-plastic fracture analysis proposed by ElectricPower Research Institute(USA)is not suitable for welded joints with mechanicalheterogeneity.This paper proposes a modification to the EPRI method and providesthe modification coefficientsC_J,C_S,C_V,for the centre cracked panels.And based onthe modification,a new enginering method for elastic-plastic fracture analysis ofwelded joints with mechanical heterogeneity is discussed. |
