Linear elasticity print that page

Equations governing a linear elastic boundary value problem are based on three tensor partial differential equations for the balance of linear momentum and six infinitesimal strain - displacement relations. The systems of differential equations is completed by a set of linear algebraic | 2011/5/4 19:06:21

Elastic modulus print that page

An elastic modulus , or modulus of elasticity , is the mathematical description of an object or substance's tendency to be deformed elastically (i.e., non-permanently) when a force is applied to it. The elastic modulus of an object is defined as the slope of its stress-strain curve in the | 2011/5/15 0:27:43

Clapeyron's theorem (elasticity) print that page

In the linear theory of elasticity Clapeyron's theorem states that the potential energy of deformation of a body, which is in equilibrium under a given load, is equal to half the work done by the external forces computed assuming these forces had remained constant from the initial state | 2011/2/9 19:57:43

Price elasticity of supply print that page

In economics , price elasticity of supply ( PES ) is an elasticity defined as a numerical measure of the responsiveness of the supply of a given good to a change in the price of that good. [ 1 ] Contents 1 Calculation 2 Interpretation 3 Determinants 4 Graphical representation | 2011/3/22 16:25:45

Constant elasticity of substitution print that page

In economics , Constant elasticity of substitution ( CES ) is a property of some production functions and utility functions . More precisely, it refers to a particular type of aggregator function which combines two or more types of consumption, or two or more types of productive inputs | 2011/3/16 0:09:04

Price elasticity of demand print that page

incidence (or "burden") of a tax on that good. Various research methods are used to determine price elasticity , including test markets , analysis of historical sales data and conjoint analysis . Contents 1 Definition 1.1 Point-price elasticity 1.2 Arc elasticity 2 History | 2011/10/4 7:43:32

Solid mechanics print that page

Solid mechanics The study of the physics of continuous materials with a defined rest shape. Elasticity Describes materials that return to their rest shape after an applied stress . Plasticity Describes materials that permanently deform after a sufficient applied stress. Rheology | 2010/10/2 1:36:58

Elasticity (physics) print that page

In physics , elasticity (or stretchiness ) is the physical property of a material that returns to its original shape after the stress (e.g. external forces ) that made it deform or distort is removed. The relative amount of deformation is called the strain . The elastic regime is ]]. | 2011/9/27 9:40:23

Partial differential equation print that page

such as the propagation of sound or heat , electrostatics , electrodynamics , fluid flow , and elasticity . Seemingly distinct physical phenomena may have identical mathematical formulations, and thus be governed by the same underlying dynamic. They find their generalization in stochastic | 2011/5/15 9:27:54

Fracture mechanics print that page


materials and components. It applies the physics of stress and strain , in particular the theories of elasticity and plasticity , to the microscopic crystallographic defects found in real materials in order to predict the macroscopic mechanical failure of bodies. Fractography is widely
