Abstract

An automated fatigue and fracture laboratory was recently set up at the National Aeronautical Laboratory. Six servohydraulic load frames are connected to a single multi-user, time-sharing computer system, through dedicated microprocessor-based interfaces. The host computer system includes resources for post processing of test data, output of test results and their storage and retrieval. Application software was developed for automated crack growth testing under a variety of constant- amplitude and spectrum load test conditions including K-control and on-line fatigue cycle analysis. Automated crack length measurement is through unloading compliance. (Author)
