The fatigue crack growth model adopted is the one due to Sih and Barthelemy, which assumes that the fatigue crack growth is controlled by the fluctuation DS of the Strain Energy Density Factor S. A simple method for obtaining approximate stress intensity factors is also applied. It takes into account the elastic crack tip stress singularity while using the elementary beam theory.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
