“…For classical elasticity with local configurations comprised of isotropic and piecewise homogeneous, linear elastic materials, all the stress singularities asymptotically identified that have been found to date since 2004 18 are discussed in the studies. Examples of stress singularities identified since 2004 for anisotropic elastic materials are given in the previous studies [63][64][65][66][67][68][69][70][71][72][73][74][75][76] ; for functionally graded elastic materials [74][75][76][77][78][79] ; for finite strain in elastic materials 80 ; and for varying size scales. 81 Of late there has been increased interest in fluid-solid interaction problems.…”

At the outset in attempting to ensure structural integrity for configurations with stress singularities, it is important to recognize their presence. In addition to the asymptotic identifications of stress singularities available in the literature, the engineer can use divergence checks in numerical stress analysis to this end. After a review of the current state of the art of asymptotic identifications, this paper outlines some divergence checks that can also be effective in this role. Once singularities are recognized, there are four options open to engineers for attempting to ensure structural integrity: relying solely on experimental testing, drawing on the experience of others for like configurations, employing a fracture mechanics approach and removing singular stresses via improved modelling. This paper focuses on the last of these options. With suitable care, the requisite improved modelling can be realized by the introduction of stress‐separation laws. Resulting stresses then offer the potential of comparing with appropriate strengths to obtain structural integrity.
