Reliability & validity
The reliability of numerical models depends on the robustness of the algorithms and the accuracy of input parameters. Validity is assessed by comparing simulation results against experimental data.
Think critically
To what extent can purely numerical modelling replace physical testing in the design and validation of composite structures, and what are the inherent risks of over-reliance on simulation?
Design Principles
"Predictive failure analysis through multi-scale numerical modelling enhances the reliability and performance of composite designs."
Understanding and predicting how composite materials fail under various loads is crucial for designing safer, more reliable, and optimized products. This allows for informed material selection and structural design, reducing the risk of catastrophic failure and extending product lifespan.
