| Abstract: | A special strain gage (PhotoStress® Separator Gage, Measurements Group, Inc., Raleigh, NC) designed to measure the sum (? 1 +? 2) of the principal strains, is used in conjunction with photoelastic-coating measurements (? 1 -? 2) to establish the value of each principal strain (? 1 and? 2). The summation strain signal is effectively independent of angular orientation (measurement direction), and by design, the gage negates soldering risks, self-heating, and localized-reinforcement considerations normally associated with strain-gage measurements on plastic parts. |
