Penetration behavior of an anchor
in sand
In this case study
an analyses is made
of the penetration behavior
of an anchor in sand.
The
following points should be taken into account.
• The geometry of
the anchor and how to simplify it.
• What happens when the anchor penetrates the soil?
• Which forces will occur during penetration?
• How to solve this mathematically?
In this website the outcome
of this research is described and the above mentioned
points
were taken into account.
First of all, the most
common anchors on the market are analyzed and a general
anchor geometry will be chosen. This chosen geometry will be simplified to a
2D
geometry,
which will be realistic for a first analysis.
After this step the penetration behavior of an anchor will
be described in different phases, such a way that it is clear and easy to understand.
Forces on the soil layer, fluke, shank and mooring line forces will be defined
and analyzed. The forces will be described as a function of the geometries including
the relevant variable angles.
In the end conclusions
and several recommendations will be given.
