Stress State in an Eccentric Elastic Ring Loaded Symmetrically by Concentrated Forces
Mathematics, 2022 The stress state from an eccentric ring made of an elastic material symmetrically loaded on the outer boundary by concentrated forces is deduced. The analytical results are obtained using the Airy stress function expressed in bipolar coordinates.

A hybrid technique for residual stress analysis through stress function fitting
Latin American Journal of Solids and StructuresThis work presents a hybrid experimental theoretical technique for residual stresses analysis of mechanical components. It was used the blind hole technique along with the Electronic Speckle Pattern Interferometry (ESPI) method and Airy stress functions ...

Differential geometric approach to the stress aspect of a fault: Airy stress function surface and curvatures [PDF]
Acta Geophysica, 2011 We considered the two-dimensional stress aspect of a fault from the viewpoint of differential geometry. For this analysis, we concentrated on the curvatures of the Airy stress function surface. We found the following: (i) Because the principal stresses are the principal curvatures of the stress function surface, the first and the second invariant ...

An exact solution for improved metal-composite joints reinforced by FG inter-layers
Science and Engineering of Composite Materials, 2017 A two-dimensional analytic solution based on linear elasticity theory is used to investigate the effect of using a functionally graded material (FGM) as an inter-layer in reducing the stress concentration in non-axisymmetric loaded metal-composite joints.

Rozwiązanie Pewnego Typu Tarczy Nieograniczonej
Engineering Transactions, 1957 A thin elastic cantilever slice is considered. The edges are straight lines and a circle. Using bipolar coordinates, the Airy function is found by separating variables and using the boundary conditions for a given function and its normal derivative at ...
