Penetration
causes fluke and shank forces.
In
this situation the fluke is completely covered by sand and the shank will
become an extra factor which will cause penetration resistance. For the shank
the cutting theory of Miedema can’t be used. The strip footing theory as described
in Verruijt will be used for determining the shank resistance. The maximum
shank resistance acts when the complete shank is penetrated.
