Abstract : Research is conducted to determine the character of stress concentrations around an unreinforced hole in cylindrical orthotropic shell sections. This report discusses construction and instrumentation of these sections with consideration of various systems of strain measurement, describes the equipment used in tests, and discusses the data obtained from strain gages epoxied to the surface of three specimens. Qualitative conclusions are drawn relating the behavior of this material to the behavior of isotropic materials and a similar glass- reinforced material with different fiber orientation.
