Stress can damage an employees' health and the business performance. Synonym of Extensional stress: English Wikipedia - The Free Encyclopedia Stress (mechanics) In continuum mechanics, stress is a physical quantity that expresses the internal forces that neighboring particles of a continuous material exert on each other, while strain is the measure of the deformation of the material. In Hollywood Rationality and popular culture generally, "rationalists" are depicted as word-obsessed, floating in endless verbal space disconnected from reality. In these calculations, we have considered the effect of a regional extensional stress field whose minimum principal axis is horizontal and oriented 216° N. For example, when a solid ve Other articles where Extensional strain is discussed: mechanics of solids: Strain and strain-displacement relations: …simple types of strain are extensional strain and shear strain. Extensional ... (3X) viscosity greatly increases the dispersive effect, breaking down the lesser component with three times the shear stress. The McKenzie model incorporates pure shear, while the Wernicke model is based upon a simple shear regime. The stress-induced transition from solid to liquid state is commonly referred to as “yielding.” Yield-stress materials, including pastes, muds, blood, crude oil, and condiments like mayonnaise, have solid-like properties at rest but can be made to yield and flow under sufficient applied stress. For example, when a solid vertical bar is supporting a weight, each particle in the bar pushes on the particles immediately below it. Work-related stress can be caused by poor work organization (the way we design jobs and work systems, and the way we manage them), by poor work design (for example, lack of control over work processes), poor management, unsatisfactory working conditions and lack of support from colleagues and supervisors. For planar exten-sional flow, η1 =ηp and η2 ≠0. Recent Examples on the Web The team only found evidence of extensional features—both ancient and modern—which suggests that a short, violent birth could have given way to an early ocean.

Viscometers determine viscosity by dividing shear stress experienced by … extensional - WordReference English dictionary, questions, discussion and forums. Shear rates are the foundation of performing viscosity experiments. However, experiments and calculations show that the dynamical response of the fluid filament is strongly dependent on the exact form of the transient extensional viscosity. Deborah Number b = 0 8 Tensile Stress Surface • The evolution of the extensional viscosity can be visualized as a function of time and strain rate. extensional phrase. s. 1. ts [] Tr (De, … Extensional Tectonic Models : There are largely two main models when considering extensional tectonics, both offering quite different proposals.

Consider a rectangular parallelepiped, a bricklike block of material with mutually perpendicular planar faces, and let the edges of the block be parallel to the 1, 2, and 3 axes. Material functions for various types of transient deformation history are pre-sented in Table I also. Extensional Viscosity Extensional Viscosity ‘stretch’ ‘coil’ Newtonian Solution Melt De = λε 0. For the relatively low extensional stress, gauche–gauche conformers that originated from the oriented amorphous chains lead to super-toughening behavior. D: Miocene extension in north China and a possible relationship with the opening of the Japan Sea (heavy arrows); single line arrow indicates Miocene convergence rate of the Pacific plate relative to the Asia continent (after Northrup et al., 1995 ).

Wagner2 This event also increased the static stress on seismogenic faults that are believed to have ruptured in the 1732 and 1857 earthquakes (M ≈ 6.5). Definition of extensional in the Idioms Dictionary. As adjectives the difference between extensional and intensional is that extensional is of or pertaining to extension while intensional is of or pertaining to intension. Polylactide (PLA) films with an excellent balance of toughness and stiffness were realized by extensional stress efficiently. Calculation of Laminate-Aluminium Extensional Stiffness Ratio: This section describes the method that was used to arrive at the stiffness parameter, E x t, for composite doublers. An extensional definition is one that identifies the members of the class it names by indicating instances of the thing being defined. We consider extensional flows which we define here as having a diagonal rate of strain tensor, D, and a diagonal stress tensor, σ. De.

Extensional flows or a combination of shear and extensional flows can happen at several situations such as in contractions and in bifurcations and when cells flow from a wide blood vessel to a narrow catheter. of Mechanical Engineering, Massachusetts Institute of Technology, Cambridge, MA 02139, USA c Polyflow, 16 Place de 1’Universite´, B-1348 Louvain-la-Neuve, Belgium The article currently says: "an extensional definition of the term 'nation of the world' might be given by listing all of the nations of the world, or by giving some other means of recognizing the members of the corresponding class." In continuum mechanics, stress is a physical quantity that expresses the internal forces that neighboring particles of a continuous material exert on each other, while strain is the measure of the deformation of the material. All Free. x and y have precisely the same members they are said to have the same extension, and sets are often called extensional entities. Who's Afraid of Jerry Vlasak? Let's consider some examples: "That" (pointing to the cup on my desk) "is a cup." For uniaxial extensional flow η1 = ηe and η2 = 0 while for equi-biaxial extensional flow η1 = ηb. extensional synonyms, extensional pronunciation, extensional translation, English dictionary definition of extensional. It's giving definitions by example. It is the stress component perpendicular to a given surface, such as a fault plane, that results from forces applied perpendicular to the surface or from remote forces transmitted through the surrounding rock. Zo kan stress bijvoorbeeld gedefinieerd worden als “een echte of een als echt gepercipieerde bedreiging van de fysiologische of psychische integriteit”(zoals geciteerd in Mcewen, 2007).
