An Introduction to Fatigue Testing at TWI

To find out more about our training courses, please visit: www.twitraining... or www.twi-global... for technical information.
Extensive testing facilities are available in four separate fatigue laboratories at TWI Cambridge, with machine load capacities in the range 2 to 2,000kN. Our experience covers the full range from simple parent material samples to bespoke full-scale tests on large structural connections, from endurance testing to fatigue crack growth rate determination, from ambient conditions to specialised corrosive environments at elevated or reduced temperature, constant or variable amplitude loading and loading frequencies from 0.001 to 200Hz. Detailed analysis and interpretation of test data is our speciality. Standard tests are covered by UKAS accreditation.

Interesting film, but obviously missing the part on stress corrosion fatigue as the most complex failure

[@vitjan4556]

The fatigue crack on the welded plate is evidently corroded and therefore of older origin. This somehow confuzes the whole video.

[@VasilyX]

Indeed it is, yet they're talking about crack growth at low stress levels, below the elastic limit. That's also a result of fatigue.

is there any fatigue testing machine for RCC BEAM ??
