Extract

In order to increase the versatility of in-situ X-ray equipment for stress measurements, we decided to design and construct our own easily transportable apparatus. Similar equipments are already commercialized: (i) in Japan (RIGAKU STRAINFLEX, SHIMADZU); (ii) in West Germany (SIEMENS); (iii) in the USA (TEC). After the commercialization of PSD or PSSC, several prototypes were developed among which, the apparatus of Ruud, James, CETIM… Our own apparatus has been developed for two main reasons:

  1. (i) For 1971, we have been working to ameliorate our own equipments effectively and frequently used for in situ measurements.

  2. (ii) We need a very precise and rapid apparatus amainable for the greatest number possible of applications.
