Numerical studies of an array of equidistant semi-permeable inclined cracks in 2-D piezoelectric strip using distributed dislocation method

An array of equidistant inclined cracks present in 2-D piezoelectric strip is numerically analyzed using distributed dislocation method (DDM). The piezoelectric strip is a cutout of an infinite domain so that the width-to-crack-length ratio is about 100 times larger than the aspect ratio of height-to-crack-length of the specimen. The inclined equidistant cracks are modeled as a continuous distribution of dislocations, and the problem is thus...
