T形接管塑性变形的测定技术和塑性载荷的确定

Measurement oF Plastic Deformation and Determination of Plastic Load for T-Shaped Nozzles

介绍了受内压和各种力矩作用的Ｔ形接管的塑性变形，用实验方法进行的测定，并对如何定义“塑性载荷”作了分析和讨论，提出了定义“塑性载荷”并符合能量准则５倍弹性斜率的方法。

Adistortional measurement was made for the plastic deformation ofT-shaped nozzles under the action of internal pressure and moments with experi-ments.Analysis and discussion were done how to definite the plastic loads.Thefive-times elastic slope method which was accorded with energy criterion waspresented for determining plastic loads.
