... iterations are usually time consuming. For the structural detail example used in the present study, numerical results show that by including the right inputs to the machine learning algorithm, the predicted fatigue life could compare well with the spectral fatigue analysis output with a score of up to 0.997...

... the seabed. Therefore, using a rigid surface to simulate the seabed and ignoring the nature of trenching development process and the effect of soil s suction are not suitable. Research points out that rigid surface generally overestimates riser s fatigue life since it is unyielding, and the nonlinear elastic...

... ABSTRACT: A novel method based upon damage mechanics is suggested to estimate the fatigue life of offshore structure members for great water depths. A new mathematical model of fatigue damage is firstly developed at University of Petroleum. China and termed Fang-Jia" s model. A macroscopic...
