Effects of breathing cracks on the dynamic characteristics of a drilling riser under irregular waves and the crack identification
To investigate the effects of breathing cracks on the dynamic characteristics, i.e., natural frequencies, vibration displacement, slope angle, and bending moment, of a drilling riser, a time-domain finite element method based on the fracture mechanics theory is developed. The correctness of the prop...
