The use of an elastic/plastic finite element computer program for the stress analysis of a notched plate fatigue specimen (TM-STM-023)

Plasticity is necessary for fatigue initiation to occur, thus an inelastic deformation analysis for stresses and strains at discontinuities is essential for accurate life predictions. Several analyses have been attempted in the past of which that of Neuber is the most satisfactory. This is an approximate method and is only...
