Journal ArticleDOI
A note on the modeling of incompressible fluids with material moduli dependent on the mean normal stress
TL;DR: In this paper, the authors discuss an error that is a consequence of not recognizing the distinction between these different quantities but misidentifying them as being the same, the mechanical "pressure".
Journal ArticleDOI
A model for a solid undergoing rate-independent dissipative mechanical processes:
TL;DR: In this paper, a thermodynamic framework is proposed to capture the dissipative response of metals, in contrast to the conventional practice, a stressed reference configuration is assumed instead of a stress-free configuration.
Journal ArticleDOI
A note on the flow of a fluid with pressure-dependent viscosity in the annulus of two infinitely long coaxial cylinders
TL;DR: The dependence of the viscosity of fluids on pressure has been well established by experiments and it needs to be taken into consideration in problems where there is a large variation of pressure in the flow domain this paper.
Journal ArticleDOI
Response of a class of mechanical oscillators described by a novel system of differential-algebraic equations
TL;DR: In this article, the authors study the vibration of lumped parameter systems whose constituents are described through novel constitutive relations, namely implicit relations between the forces acting on the system and appropriate kinematical variables such as the displacement and velocity of the constituent.
Journal ArticleDOI
Upper and lower bounds for the pressure error in the rectilinear flow along a slot with a pressure gradient
TL;DR: In this paper, the rectilinear flow of a second-order fluid is considered between two infinitely wide and long parallel plates, where the bottom plate is at rest and has a longitudinal slot in the direction of the flow, while the top plate moves in the flow direction with a constant speed.
