Article: “Better predictions of the working life of industrial components”
“A minor disparity between an established mathematical model to predict creep crack growth behavior in materials in high-temperature environments and actual data has prompted Dr. Warwick Payten to reassess the approach and revise the model.”
“Being able to more accurately predict crack growth in real components is highly useful because it allows you to potentially extend the life of operating industrial plants and conventional, solar and nuclear power stations with confidence,” said Payten, a senior nuclear fuel cycle researcher.” https://phys.org/news/2020-04-life-industrial-components.html
This use of a mathematical model to predict failure in industrial materials is well-suited for November TOK essay Prescribed Title #6. Applied mathematics is a field where there are numerous issues of reliability and certainty.
