DWT 245: Everstine's collection
Carriage

from set DWT, from the Harwell-Boeing Collection

The finite element model that generated this matrix contains 245 nodes, 518 beam elements, 35 triangular plate elements, and 34 quadrilateral plate elements. The model is shown below. Plate and solid elements are outlined in black. Beam and rod elements are drawn as tubes. The carriage is based on similar structures used in the towing basins at NSWC, Carderock Division.
