The Brewster ('''B''') is a unit used to measure the susceptibility of a material to Photoelasticity , or the value of the Stress Optic Coefficient of the material. The unit has dimensions reciprocal to those of stress. One Brewster is defined to be equal to Square Metre s per Newton (m²/N or 1/Pa) or Square Centimetre s per Dyne (cm2/dyn). The unit is named after David Brewster , who discovered stress-induced Birefringence in 1816 . EXTERNAL LINK |
