A method is proposed for simplified nondestructive evaluation of multiple cracks by means of the d.c. potential drop technique for a subregion containing some cracks. The distribution of the potential drop for cracks, except for end cracks, in a subregion is measured and calculated by assuming values for the depths of the end cracks and by assuming arbitrary values for the depths of other cracks. The calculation is based on simplfied analysis of crack interactions. Modification of the depths of the other cracks is repeated until the difference between measured and calculated potential drops is minimized, where the depths of the end cracks are fixed. The analysis can be done in a short time using a personal computer. It is shown that the evaluated crack depth is in good agreement with the actual one.
