Inhomogeneities of Minimum Stress Concentration
Mathematics and Mechanics of Solids, 2004The problem of finding the shape of an elastic inhomogeneity that minimizes stress concentration is investigated. A class of ellipsoidal inhomogeneities is identified that serve as minimizers for inclusions which aie softer than the matnx. For hard inclusions, strain minnnimzing ellipsoidal inhormogeneilies are described.

Stress concentration in an elastic body may be caused mainly by the two-mechanisms i.e., concentrated forces acting to a body and geometrical discontinuities of a body such as holes or abrupt change of its surface geometry. The local stress increase induced by stress concentration sometimes causes the initiation of a fatigue crack in a structure, which

Stress Concentration in Concrete
Nature, 1964IN carrying out some experimental work in the torsion of hollow concrete box beams, the authors were surprised to discover that the size of the fillet radius at the internal corners has little or no effect on the strength of the section. That is to say that in practice, although not in theory, there was no measurable stress concentration effect.

Stress Concentrations in Fillets
1953The stress concentrations arising in the fillets of fan and turbine blades, tie down rods, and bolt heads from axially symmetric centrifugal or static force loadings are treated two dimensionally by photoelastic and theoretical methods. The effects of the fillet radius, the height of the base, the mode of application of retention forces, and the ...

Journal of Cell Science, 1962
ABSTRACT Small cavities and notches in an otherwise perfect material will greatly reduce the strength of the material, particularly its tensile strength. They will do this by producing stress concentrations around themselves. It is shown that bone is permeated with such stress-concentrators in the form of canaliculi, osteocyte lacunae ...
