Damage Detection of Bridge Using Vibration Analysis and Finite Element Method
Dear All,
I am currently working on a small academic project of Damage Detection of Bridge Structure using Vibration Frequency and Modes analysis and Finite Element method.
My questions are:
1) Is there any systematic approach to follow this problem?
2) How should I start making its mathematical model? I am considering a truss bridge. Is it appropriate to consider linear elastic deformation of simply supported beam at first point?
3) Is there any standard reference which can help me to construct its mathematical model?
George Bugliarello died on 18 February 2011
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.
Stress intensity factor
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
