Two-dimensional experimental elastic-plastic strain and stress analysis

Barbara Kozłowska

Abstract

In the paper, the quantitative analysis of elastic-plastic state of strain and stress in two- dimensional models with different stress concentrators is p resented. The experimental testing was carried out by the photoelastic coating method on duralu min elements loaded by tensile stresses. For strain separation, the analytical method of c haracteristics, taking advantage of an isochromatic pattern only, was applied. The strain and st ress components in elastic-plastic areas around stress concentrators were calculated using th e multi-sectional schematization of the material curve. The effects of investigations have bee n compared with those obtained from Moir ́e method and numerical calculation (FEM). The dis cussion of results has been presented.
