Present state of experimental stress analysis by strain gages in Japan

This paper describes the present state of strain gages, measuring devices and stress-cycle counters in Japan. Details are given to the following items: (1) electric-resistance-wire strain gages, (2) vibrating-string gages, (3) magnetostriction gages, and (4) stress-cycle counters. Items (1) and (2) manufactured in Japan are comparable to those manufactured in other advanced countries. Item (3) was specially developed in Japan. Research on item (4) is now in progress.This Field Report is based on a paper presented, by title only, at the 1960 SESA Spring Meeting held in Indianapolis, Ind., on May 18–20.
