Lecture Notes on Constant Elasticity Functions
Lecture Notes on Constant Elasticity Functions Thomas F. Rutherford University of Colorado November, 2002 1 CES Utility In many economic textbooks the constant-elasticity-of-substitution (CES) utility function is defined as: U(x,y) = (αxρ +(1−α)yρ)1/ρ It is a tedious but straight-forward application of Lagrangian calculus to demonstrate ...

MODULUS OF ELASTICITY The modulus of elasticity (= Young’s modulus) E is a material property, that describes its stiffness and is therefore one of the most important properties of solid materials. Mechanical deformation puts energy into a material. The energy is stored elastically or dissipated

An example is shown in Fig. 6.3.2a, which shows a glass-fibre composite material. The material consists of thousands of very slender, long, glass fibres bound together in bundles with oval cross-sections.
