Equivalence rule and transonic flows involving lift

11th Aerospace Sciences Meeting, 1973
Abstract : The transonic flow around a thin and smooth configuration with swept leading edge is shown to possess an outer nonlinear structure determined principally by an equivalent line source and an equivalent line doublet. In the lift dominated and intermediate domains there is an important nonlinear lift contribution to the equivalent source, which

Shakedown with Non Associated Flow Rule

2002
First, we present the concept of bifunctional which allows to extend the calculus of variation in case of a material admitting a bipotential. Next, the bound theorems of the shakedown analysis are generalized for this class of plastic materials. The key of the proof is that the normality rule is conserved but in an implicit form.

Backend CAD flows for "restrictive design rules"

IEEE/ACM International Conference on Computer Aided Design, 2004. ICCAD-2004., 2005
To meet challenges of deep-subwavelength technologies (particularly 130 nm and following), lithography has come to rely increasingly on data processes such as shape fill, optical proximity correction, and RETs like altPSM. For emerging technologies (65 nm and following) the computation cost and complexity of these techniques are themselves becoming ...

The associated flow rule of plasticity

Journal of the Mechanics and Physics of Solids, 1957
Abstract The workhardening and linearity hypotheses introduced by Drucker are logically equivalent to the hypotheses of the existence of the plastic potential and of its identity with tlie yield function. Since neither of these sets of hypotheses is deducible from established physical laws, the author suggests that they are alternative statements

New Rules for DSM Flows

2003
New process options have posed a new problem in the selection of target technologies for migrated data. The discussions that follow are targeted to address like processes and are intended to cover the additional details of device change migration. Some of these device change migrations include traditional CMOS designs being ported to a SiGe process ...

Failure criteria and flow rules of geomaterials

Revue Française de Génie Civil, 2004
ABSTRACT Essentially because of the non-associative character of geomaterials plastic strains, many bifurcations leading to various failure mechanisms exist strictly inside the plastic limit condition. The equations of the boundaries of the failure domain and of the cones of unstable stress directions are first exhibited for axisymmetric conditions ...

The extended flow rule in plasticity

International Journal of Plasticity, 1997
In order to construct a pertinent model for a general loading process, the author employs an extended flow rule, constitutive equations for metals, and comparisons with numerical calculations and experimental data. Besides, the theory proposed includes the dependence of magnitude and direction of plastic stretching on stress rate, the reversible ...
