Strengths & Limitations

Strengths

+Development of a novel computational framework for EBM optimisation.
+Rigorous validation through case studies and experimental testing.

Limitations

Simulations are only as good as the data they are based on. Real-world manufacturing can have variations that are difficult to perfectly model, so experimental testing is still essential.

Reliability & validity

The study's reliability is supported by the use of established numerical simulation techniques (finite strain theory, membrane formulation). Validity is enhanced through extensive experimental validation with both idealised and complex industrial product case studies.
