Plow
blade shape optimization-In order to examine whether the cutting
edge of plow blades could be optimized for ice removal, the mechanics
of removing a thin brittle layer (ice) from a strong substrate (pavement)
was studied. This study involved the finite element modeling of
the ice layer and pavement, and the fracture mechanics associated
with debonding the ice layer. The results of this study indicated
that an optimized profile of the cutting edge would be nearly vertical,
and that the strength of the bond between the layer and substrate
was the most important factor controlling ice removal. Magnetoelastic
deformation and buckling-The
deformation and buckling of ferromagnetic structural members placed
within magnetic fields was examined in this work, which developed
a method to allow the local magnetic field strength at the surface
of a structural member to be calculated. Using this field, the forces
resulting from the magnetic field could be accurately characterized
and the deformation predicted. While earlier studies had resulted
in predictions of the magnetic field strength required to cause
buckling that were 50 to 100 percent in error, the buckling fields
predicted by this new model were virtually identical with experimentally
measured values.
