Abstract
This paper introduces a new testing method developed by Okuboet el. which is used to control a linear combination of force and displacenlent. It was implemented on a specially designed servo-controlled testing system and a MTS machine successfully.The method may be used for many testing purposes concerning the mechanisms of weakening processes. Complete stress-strain curve can be obtained by this method and its application gives some testing methods such as generalized relaxation test, which may be used to investigate time-dependent failure behaviour ofrock.
