MOHR ELLIPSE DIAGRAM NET METHODS OF FINITE STRAIN MEASUREMENT

When people use fossils or veins as strain marks, they often obtain result by mathematic computation or Mohr ellipse diagram method. The both methods not only have the complicated operation steps, but also consume much time. In this paper the author has designed a kind of Mohr ellipse diagrament, the structure of the net is similar to that of the pole equal angle net, but physical meanings of the every elements are different between both of them. The operation of the net is brief, and we can obtain exact result rapidly with the net. Besides this, questions of stress analysis can be also solved with the net.
