Aged Structures - Fatigue Life Assessment

RTA provides fatigue life assessment of machine structures, based on proposed duty cycles and/or historical data. Related projects include wagon chassis structures, wagon tipplers and container cranes. The outcomes resulting from RTA's fatigue life assessment include the current risk of fatigue failures within the structure and forecasts of how this risk is expected to change over the remainder of the desired service life. To accompany this information, focused inspection regimes have been developed to assist with the continued management of the asset in question.  Rockfield has also provided design solutions to ensure extended duty and safe operation over the period of desired service. Images of two signature design analysis projects are shown below:

Investigative Engineering (Root Cause Analysis)

Rockfield has adapted their knowledge of materials, metallurgy and practical engineering analysis to combine with high technology tools (FEA) to conduct investigative analysis of mechanical and structural failures. RTA's experience in this field has extended to hydraulic cylinder failures, large and small cast component failures, concrete beam structures and product defect analysis.  Rockfield complements their investigative engineering service with a range of physical material testing capabilities (tensile testing, bending, hardness, Charpy impact), together with forensic analysis using scanning electron microscope and X-ray fluorescence technology.
