<P>PROBLEM TO BE SOLVED: To provide a strength evaluation method for a layer structure capable of easily and accurately evaluating interlayer strength in a layer structure having a curvature. <P>SOLUTION: This strength evaluation method for a layer structure measures interlayer strength of a layer structure having a curvature. In this method: a test piece 12 having the curvature is cut out from the layer structure; the test piece is supported at support points 12a and 12b in between which the part having the curvature is held; and an interlayer stress of the test piece 12 is measured by applying a load (arrows A, B) between the two support points 12a, 12b of the test piece 12, acting in such a direction that makes the curvature smaller. <P>COPYRIGHT: (C)2012,JPO&INPIT |
