Photoelasticity print that page


The photoelastic phenomena was first described by the scottish physicist David Brewster [ 1 ] . [ 2 ] Photoelasticity developed at the beginning of the twentieth century with the works of E.G.Coker and L.N.G Filon of University of London . Their book Treatise on Photoelasticity published

Optics print that page


Most optical phenomena can be accounted for using the classical electromagnetic description of light. Complete electromagnetic descriptions of light are, however, often difficult to apply in practice. Practical optics is usually done using simplified models. The most common of these, geometric

Contact mechanics print that page


Contact mechanics is foundational to the field of mechanical engineering ; it provides necessary information for the safe and energy efficient design of technical systems and for the study of tribology and indentation hardness . Principles of contacts mechanics can be applied in areas such

Acousto-optics print that page


of imaging. [ edit ] The acousto-optic effect The acousto-optic effect is a specific case of photoelasticity , where there is a change of a material's permittivity , , due to a mechanical strain a . Photoelasticity is the variation of the optical indicatrix coefficients B i caused by

Dislocation print that page


In materials science , a dislocation is a crystallographic defect , or irregularity, within a crystal structure . The presence of dislocations strongly influences many of the properties of materials. The theory was originally developed by Vito Volterra in 1905 but the term 'dislocation' was

Stress analysis print that page

The aim of the analysis is usually to determine whether the element or collection of elements, usually referred to as a structure, can safely withstand the specified forces. This is achieved when the determined stress from the applied force(s) is less than the ultimate tensile strength , ultimate | 2011/7/12 9:29:41

James Clerk Maxwell print that pageTimeline of James Clerk Maxwell


Maxwell demonstrated that electric and magnetic fields travel through space in the form of waves , and at the constant speed of light . In 1865 Maxwell published A Dynamical Theory of the Electromagnetic Field . It was with this that he first proposed that light was in fact undulations in

Lithium niobate print that page

lacks inversion symmetry and displays ferroelectricity , Pockels effect , piezoelectric effect, photoelasticity and nonlinear optical polarizability. Lithium niobate has negative uniaxial birefringence which depends slightly on the stoichiometry of the crystal and on temperature. It | 2011/7/14 6:00:54
