Book excerpt: Relations between the strain energy density distribution and the elastic-plastic strain-stress fields near notches have been analyzed. It was found that the strain energy density distribution in the plastic zone ahead of the crack or notch tip can be satisfactorily estimated on the basis of the theoretical elastic stress field. The strain energy density can be translated into the elastic-plastic strain and stress in the plastic zone if the nonlinear material stress-strain curve is known. Good agreement with finite element calculations has been achieved for cracks under plane strain conditions. It has also been shown that the equivalent strain energy approach can be useful for the notch-tip elastic-plastic strain calculation under both monotonic and cyclic loading.
