This article deals with the local quality on stresses produced during finite element analysis in 3D linear elasticity. We use an estimation technique based on the concept of error in constitutive relation, which yields excellent estimates of the local errors without requiring the approximate calcula

In this paper the shear deformable shallow shells are analysed by boundary element method. New boundary integral equations are derived utilizing the Betti's reciprocity principle and coupling boundary element formulation of shear deformable plate and two-dimensional plane stress elasticity. Two tech
The expressions of stress-strain field in a finite plate with crack-tips of different radii of curvature have been derived by the method of conformal mapping-weighted residues. The stress-strain field has been evaluated for the LYIZM piate of dimensions 300 mm x 150 mm x 2 mm under uniaxial tension.
Plates with centraI through cracks subjected to bending is analysed taking into account the closure of ihe crack faces on the compression side. A r~ee-dimension finite element method emplo~g t~ee~~ensjon~ degenerate SOB element is used for the amdysis. The crack faces have been mode&d such that they
