Insights into Digital Twins

The Design and Manufacturing Futures laboratory, based at the University of Bristol, is researching and creating the tools and technologies of tomorrow, providing game-changing capability for the design, manufacture, operation and disposal of next generation products and machines. While very often based on a virtual prototype (inc. multi-physics) a digital twin has: a role beyond […]

Probabilistic treatment of stresses for use in creep-fatigue crack initiation assessments

Research Area: Structural Integrity PI: Mr Nader Zentuti Funders: EDF Energy Contact details: The Challenge For assessing a component operating at high temperatures for creep-fatigue damage which can lead to crack initiation, the stress state during nominal operating conditions is required. These stresses are usually obtained from complex thermal and mechanical FE. However, using […]

Creep Deformation and Damage During Stress Relaxation in Stainless Steel Weldments Operated at High Temperature

Research Area: Structural Engineering PI: Mr Satyajit Dey Funders: EDF, Atkins Contact details: The Challenge Many engineering steel components used in power generation plants are operated at creep regime temperatures. This means that the steels are susceptible to creep and stress relaxation. It is important to estimate the amount of creep strain accumulation during […]
