White paper – Fracture and Fatigue Crack Growth

This whitepaper discusses the application of numerical modelling for the calculation of fracture parameters for Fitness-For-Service assessments. The shortcomings of analytical solutions presented in assessment codes, and the requirements for high degrees of accuracy of calculated fracture parameters, are discussed. The main two solid mechanics numerical techniques are briefly outlined and two commercially available fracture

Fatigue Assessment of Welded Joints

1. PROBLEM DESCRIPTION Deacon Engineers carried out the design of large, rotating digesters for the treatment of municipal solid waste. The digesters are approximately 65m long and 4.5m in diameter and rotate continuously, at 1 rpm, while processing up to 500 tonnes of waste. Due to the cyclic nature of the loading, careful attention had
