Analysis of Nonlinear, Dynamic Coupled Thermoviscoelasticity Problems by the Finite Element Method. (1998)

Oden,J. T., Armstrong,W. H.

The investigation deals with the numerical solution of a class of nonlinear problems in transient, coupled, thermoviscoelasticity. Equations of motion and heat conduction are derived for finite...

Fluorine-19 chemical shifts as structural probes of metal-sulfur clusters and the cofactor of nitrogenase.

Mascharak, P K, Smith, M C, Armstrong, W H, Burgess, B K, Holm, R H

Several properties of the FeMo-cofactor (co) of nitrogenase in N-methylformamide solution at ambient temperature have been investigated by means of 19F NMR spectroscopy. With C6H5CF3 reference...
