measures deformation and normal force for a sample under an applied
torque. Operation modes include creep and recovery, oscillatory shear, and
constant stress. Gap is controlled automatically on Model CVO, and manually on Model CS.

Eleven-Decade Dynamic Mechanical Analysis
developed by Professor Lakes, this solids testing apparatus measures
the storage and loss moduli over 11 decades of test frequency.
a fluid dynamics analysis package based on a general purpose finite
element code to simulate mostly Newtonian incompressible flows in complex
geometries, including the effects of temperature and the presence of chemical
a research finite element code developed at the University of
Wisconsin-Madison to investigate the behavior of single-integral, non-Newtonian
constitutive models in incompressible, steady flows in complex geometries, using
FIDAP as a "front-end."
a general computational fluid dynamics package based on the finite volume method. It has capabilities for Newtonian laminar and turbulent flows with phase transitions, heat and mass transfer and chemical reactions, as well as some non-Newtonian flow capability.
software to analyze rheological data from many rheometers and to determine rheological parameters using Winter's parsimonious technique. Includes time-temperature superposition and conversion of dynamic data into linear relaxation spectra.
