    Abstract

    Conventional FCP test procedures were developed Mainly for constant amplitude loading. With a view to cater to the two additional requirements described above, procedures were recently developed at NAL for fully automated FCP testing under random load sequences. They permit stress and K-controlled testing under any given load sequence including constant amplitude, programmed block, arbitrary peak/trough and Markov Matrix based random loading. This paper describes features of test software and hardware developed for random load testing with K-control, crack length and crack opening/closing load measurement and on-line Modification of test load sequence through rainflow analysis.
