Stress Analysis on Cannonballs during Collision onto Sea Surface

Abstract:

When a cannonball collides with sea surface, an impulse force acts on the cannonball. Since the colliding occurs in a very short period of time, it is extremely unsteady. In order to find out if the cannonball fractures, analysis is performed to calculate the stress on the cannonball shell. In this study, an impulse force is applied to the elements of the cannonball colliding with sea surface and the analysis considers various collision conditions.
