Enhancement in Capabilities of Computer Code 'CRACK' and Case Studies.

摘要

The computer code 'CRACK' is capable of fracture mechanics analysis of 2-D bodies. The capabilities of this code has now been enhanced by adding few more crack-tip elements and different methods of computing stress intensity factor. A number of case studies are also done to show the variety of problems this code can handle. A few of them are of direct practical interest. Present report details this work and future work planned in this area. (author). 12 figs., 11 refs. (Atomindex citation 20:007764)
