要旨:
This thesis describes a way of modeling viscoelasticity in deformable solids
for interactive haptic and display purposes. The model is based on elastostatic
deformation characterized by a discrete Green's function matrix, which is
extended using a viscoelastic add-on. The underlying idea is to replace the
linear, time-independent relationships between the matrix entries, force, and
displacement with non-linear, time-dependent relationships. A general framework
is given, in which different viscoelastic models can be devised. One such model
based on physical measurements is discussed in detail. Finally, the details and
results of a system that implements this model are described.
