一般注記This paper deals with the analysis by the moire method of strain distribution on a plane of fiber reinforced composites with high rigidity. The strain distribution is determined from moire fringe patterns and an electrical resistance strain gage, or fringe patterns which are obtained by a testing procedure using combined specimens. The fringe patterns are obtained by a fringe reconstructer which is an optical spatial filtering system with coherent light. The method is applied to analysis of strain distribution in strips of aluminum alloy and epoxy resin, with a circular notch, under tension. A comparison of the results with values of theoretical analysis confirms that the method is appliciable to the determination of strain distribution on a plane of rigid structural materials, such as composites. Moreover, the method can be applied to the analysis of strain distribution in tension tests of various kinds of composites, i.e., glass cloth-epoxy, glass fiber-polyester, graphite fiber-epoxy and graphite cloth-epoxy composites, with circular or semi-circular notches. Using the results of the above mentioned tests, this paper discussed the influences of the notch on the mechanical properities of material under tension for each of the above composites.
