摘要
提出了面内云纹法应变符号判断的两种新方法──零级法、同级法。零级法是根据零级云纹所处云纹图的特殊位置，如一角、一端来判断应变符号的方法；同级法是根据相同级数云纹间所夹云纹即为，都为零的线来判断应变符号的一种方法。这两种方法分别在纯剪切和山字型构造应变分析中得到成功的应用。
Two new methods of judgement of strain sign in analysis with in- plane moire method are presented in this paper.They are called as zero order method and same order method respectively.In the zero order method,the special location (such as at a corner or an end) of zero order moire fringe is used.In the same order method,a moire fringe between two fringes of same order is considered to satisfy.The two methods are successfully applied to in- plane moire analysis of pure shear and epsilon- type structure,respectively.
