请教板单元赋属性问题
给板单元赋属性时，Input Properties面板中的、和各代表什么意思？我看到一个讲稿中说和都填0时，后处理中Position选At Z1时输出的von Mises应力就是板单元的中面应力，是这么回事吗？Plate Offset就是节点所在的面距离实体中面的距离；
Fiber Dist.1：Fiber distances for stress calculations. The positive direction is determined by the
right-hand rule, and the order in which the grid points are listed on the connection
entry.The default for Z1 is -T/2, and for Z2 is +T/2. T is the local plate thickness defined either by T on this entry or by membrane thicknesses at connected grid points, if they are input on connection
entries. supermenxp 发表于 2013-4-9 00:16 static/image/common/back.gif

这个是从Nastran快速参考手册里面摘抄下来的吧？谢谢你的回答！ 我这边是DIST 1填0，最终结果，就代表Z1是中面应力，，提取中面应力选择“At Z1"。。
