Numerical and experimental analysis of plastic deformation in the vicinity of the crack tip
Original language description
In the first section, the rate of strain energy under loading of a crack specimen will be discussed, followed by a discussion of numerical analysis of plastic fields in the vicinity of the crack tip, and finally a comparison with an experiment carried out by an optical method of deformed circle. Since the results (e.g. force vs. displacement) obtained from the experiment and analysis did not match well, a correction of the stress-strain curve was carried out. The original stress-strain curve was derivedfrom a smooth round bar tensity test but in the vinicity of the crack tip occurs different state of stress, than that in round bar. Thus, the values of calculated and measured strains in selected places in the vicinity of the crack tip had been observedand the stress-strain curve had been modified until a certain allowed difference was achieved. The force vs. displacement dependence was then again calculated for the modified stress-strain curve.
