The Delft Sand, Clay & Rock Cutting Model

---

This book gives an overview of cutting theories for the cutting of sand, clay and rock as applied in dredging engineering. In dredging engineering in general sand, clay and rock are excavated with buckets of bucket ladder dredges, cutter heads of cutter suction dredges, dredging wheels of wheel dredges, drag heads of trailing suction hopper dredges, clamshells, backhoes and other devices. Usually the blades have a width much larger than the layer thickness of the cut (2D process) and the blade angles of these devices are not too large in the range of 30°-60°. Although clamshells and backhoes may have blade angles around 90°when they start cutting. Other devices like drill bits of oil drilling devices,blades of tunnel boring machines,ice berg scour and the bull dozer effect in front of a drag head may have cutting angles larger than 90°. In such a case a different cutting mechanismis encountered, the so called wedge mechanism
