Over-critical load analysis for residual stresses and displacement around fastener-holes based on the decohesive failure mechanism and non-linear Mises yield criterion

Analytical calculations of residual stresses and displacement in the case of elevated loads applied to common engineering structures require particular attention. This is related to various types of singularities such as material and geometrical discontinuities or numerical errors, particularly, for elastic/perfectly-plastic material. In the present study, some important aspects leading to such singularities are discussed within the framework of small strains and plane-stress state. Structures such as double-shear bolted connections, shrink-fits, open fastener-holes and pressurized rigid containers are analyzed based on the classical problem of an annular plate with a central hole subject to uniformly distributed inner pressure. At the outer edge, the plate is either stress-free or embedded into a rigid container. Comparison of the results with related papers is provided.
