According to Fredholm's theorem, this paper proves that due to the virtual fundamental loads -which satisfy the boundary conditions and being distributed outside the elastic body occupied region, the displacement and the stress fields in the elastic body occupied region are unique. This theorem forms a theoretical basis of the applications of the line-loaded integral equation method.

The investigation of influence of a single tensile overloading on the fatigue crack growth rate of 16 Mn steel was made. Specimens employed were center-crack test (CCT) plates. The stress ratio, R, of baseline load was zero. The investigation includes effects of the overload stress ratio and of the crack length at which the overload was applied. Investigation results gained agree fairly well with the previons work done, i. e. The retardation would increasing with increasing cverload stress ratios, but decrease...

The investigation of influence of a single tensile overloading on the fatigue crack growth rate of 16 Mn steel was made. Specimens employed were center-crack test (CCT) plates. The stress ratio, R, of baseline load was zero. The investigation includes effects of the overload stress ratio and of the crack length at which the overload was applied. Investigation results gained agree fairly well with the previons work done, i. e. The retardation would increasing with increasing cverload stress ratios, but decrease with increasing crack lengths when overload. The Willenborg model as well as the Matsuoka model were employed to estimate the retardation and their mutual comparisons were also made. It is shown that the Willenborg model gives a good approximation to the experimental data, when the overload stress ratio is low, howere, when the overload stress is high, the results will go rather far from the experimental data, moreover, the deviations would incline to the unsafe side. Retardation effects estimated from the Matsuoka model would show a good approximation to the experimental data, even the deviating ones would incline to the safe side. It is then considered that the Matsuoka model is a good model capable to be used with profit to estimate the retardation effects of overloading in 16 Mn steel.
