“…These formulas are derived based on regression algorithms using the results of 7500 tensile results, including static and dynamic loads, with various types of steel such as SS41, AH36, HSLA, HY-80, HY-100, etc. These formulas have been successfully applied and demonstrated accuracy and reliability in offshore structures such as drilling platforms [17][18][19][20], submarines [21], and wind turbine foundations under collision scenarios [22]. It should be noted that for collision problems, the material response strongly depends on the strain rate.…”

“…A friction coefficient of 0.3 is applied between the falling weight and the impacted object to ensure no sliding occurs between the two surfaces during the collision. The Rayleigh damping model is employed for the post-collision vibration analysis [18][19][20][21][22][23]. After the completion of the collision simulation, all models are transferred to the residual strength simulation after the collision.…”

“…Furthermore, Lee et al [25] optimized a composite cylinder under external hydrostatic pressure. Do et al [26] derived an empirical equations to predict the residual ultimate strength of both stringer and ring stiffened cylinder under hydrostatic pressure, moreover found that the stringer-stiffened cylinder was failed due to the local buckling at the stringer stiffener panels, whereas the ring-stiffened cylinder was failed due to the overall buckling mode. Wei et al [27] optimized the cross-sectional shape of the stiffeners of a composite pressure hull to improve the stability and maximize the buckling pressure and found that the stability was improved when the bottom angle of the trapezoidal stiffener is nearly one hundred degrees.…”
