A study of notch fatigue Part I, static photoelastic measurements
Lindsey, Gerald Herbert
MetadataShow full item record
A careful facility calibration of photoelastic measurements on uniaxial tension specimens containing stress concentrations was conducted. Thorough characterizations of both mechanical and optical properties were made in preparation for notch studies in the linear and nonlinear regimes. As a part of the work, a new elasticity solution is obtained to evaluate the effect on stress levels at the notch of Poisson's ratio mismatch between coating and specimen. (Author)
