โœฆ Synopsis

Abtmct

-An internal crack problem in a semi-intktite plane under uniform tension is taken as a sample problem to estimate accuracy for the calculated stress intensity factors (SIF). The problem is reduced to a solution of the singular integral equation. After the approximate solution of the singular integral equation and SIF values at crack tips are obtained, the tractions at very dense discrete points on the crack face can be evaluated. From the deviation between the calculated tractions and the given boundary tractions along the crack face, the numerical estimation of accuracy for calculated stress intensity factors can br! carried out stately. Finally, the eakxiated numerical results are presented.

The fatigue and fracture performance of a cracked plate can be substantially improved by providing patches as reinforcements. The effectiveness of the patches is related to the reduction they cause in the stress intensity factor (SIF) of the crack. So, for reliable design, one needs an accurate eva
