Initial Static Analysis

From the initial static analysis, the bending moment distribution is shown in the figure below.

Initial Static Moments

Dynamic Analysis

Sample dynamic results are given in the figures below. The bending moment envelope for the riser is shown in presented in the Bending Moment Envelope figure. The maximum moment naturally occurs in the contact region. The Bending Moment Time History figure below presents a time history of bending moment for location experiencing the greatest moment.

Bending Moment Time History

The two figures below present the total contact reaction and impulse, respectively, as a function of time. Note also that the clearance/interference analysis predicts an impact velocity of approximately 14.5m/s.
