摘要：
The problem of a beam containing a semi-elliptical surface crack and subjected to tension or bending loading is investigated. The stress-intensity factor along the crack front can be calculated assuming a model with finite strips arranged in series and parallel. Several cases are analysed varying the crack sizes, that is to say, different aspect ratios and relative crack depths are considered.
