63 Introduction • Previously, semi-elliptical and surface arbitrary cracks pre-existed. Now, with the work Somasekhar Kota did, we have new types of crack objects – namely elliptical, ring and embedded arbitrary cracks. • We used to draw a half-torus in case of semi-elliptical cracks with two spider nets drawn at the ends of the half-torus tube. Now, in case of elliptical cracks, we draw the complete torus with just a single spider net, which indicates and corresponds to the element size set in the details and matches with the mouse cursor net. • For surface arbitrary cracks, the origin of the coordinate system would be on the surface of the body and the buffer zone box would be only drawn in the positive X- axis (towards inside of body). But now, with embedded arbitrary cracks, the coordinate system lies inside the attached body and as a result, we extend the buffer zone box in the negative X-axis with the same amount as in the positive X-axis.
