✦ Synopsis

This paper describes the application of super element technique to the study of crack closure phenomena in the case of an inclined crack. The influence of closure load on closure length and mode I and mode II stress intensity factors for an inclined crack are studied in detail. The other parameters which are taken into account are the position of closure load and the angle of crack. Transformation matrix technique has been found to be highly convenient for applying the constraints, especially when combined with the frontal solution technique.
