Robert C. Armstrong mainly focuses on Constitutive equation, Thermodynamics, Mechanics, Shear flow and Viscosity. In his work, Cauchy stress tensor is strongly intertwined with Stress, which is a subfield of Constitutive equation. When carried out as part of a general Thermodynamics research project, his work on Viscoelasticity, Constant Viscosity Elastic Fluids and Kinetic theory of gases is frequently linked to work in Bar, therefore connecting diverse disciplines of study.
His Viscosity research is multidisciplinary, incorporating elements of Newtonian fluid and Classical mechanics. His research integrates issues of Non-Newtonian fluid and Fiber in his study of Newtonian fluid. Robert C. Armstrong has researched Finite element method in several fields, including Mathematical analysis and Stagnation point.
Robert C. Armstrong spends much of his time researching Mechanics, Classical mechanics, Constitutive equation, Viscoelasticity and Newtonian fluid. As part of one scientific family, he deals mainly with the area of Mechanics, narrowing it down to issues related to the Viscosity, and often Drag. His Classical mechanics research includes elements of Couette flow and Steady state.
His study in Constitutive equation is interdisciplinary in nature, drawing from both Shear flow, Stress and Mathematical analysis. His Viscoelasticity research incorporates elements of Elasticity and Flow birefringence. The concepts of his Newtonian fluid study are interwoven with issues in Rotation and Shear thinning.
His primary areas of investigation include Liquid crystal, Mathematical analysis, Statistical physics, Distribution function and Diffusion equation. His research in Liquid crystal intersects with topics in Flow and Shear flow. His Mathematical analysis research incorporates themes from Viscoelasticity and Short term stability.
His Distribution function research includes themes of Discretization, Pipe flow and Maxima and minima. His studies deal with areas such as Couette flow and Cascade as well as Thermodynamics. In his research on the topic of Rheology, Mechanics is strongly related with Microscale chemistry.
His primary areas of study are Isotropy, A priori and a posteriori, Thermodynamics, Liquid crystal and Mechanics. His studies deal with areas such as Finite element method, Classical mechanics and Maxima and minima as well as Isotropy. His Thermodynamics research is multidisciplinary, relying on both Sharp interface, Mathematical analysis, Binary alloy and Minification.
His Liquid crystal study combines topics from a wide range of disciplines, such as Bifurcation diagram and Bifurcation. Robert C. Armstrong studies Shear stress, a branch of Mechanics. His biological study spans a wide range of topics, including Shear, Shear flow and Vorticity.
