George Bugliarello, president emeritus and former chancellor of Polytechnic Institute of New York University (NYU-Poly), an acknowledged visionary who brought about significant changes in engineering and education, died after a short illness on February 18.  He was trained in hydrodynamics and civil engineering.  His lifelong investigation was  how natural, mechanical, information and energy systems affect society.   

hi all,

I am facing problem in understanding stress intensity factor. How exactly i can analyse crack propagation through SIF. In books it is given that SIF characterises the crack. But in numbers how can i know whether this crack will propagate for this value of SIF. According to westergaard equation crack tip stresses will go to infinity if θ and r tends to zero for any value of crack length. Please somebody help regarding this. If iam technically wrong please correct me.

Thank you
