Abstract:

According to a method for transforming a three dimensional problem of a single elliptical hole in an anisotropic material to a problem of a circular hole in a different anisotropic material, we can treat the first boundary value problems in a laminate with an elliptical hole especially its free edge effect, if the problem with a circular hole has been solved.

Key words: composite laminate, elliptical hole, free edge effect, three dimensional stress
