Ms. Sarah Bagnall

Ms. Sarah Bagnall is a materials engineer expert specializing in materials failure analysis. With a career encompassing forensic engineering, thermal degradation analysis, and metallurgical analysis, she brings a nuanced understanding of material integrity to litigation work. Her work centers on investigating material failures, assessing thermal degradation in austenitic steels, and evaluating whether metallurgical deviations contributed to structural failures.

Ms. Bagnall has been retained in numerous expert witness and consulting engagements across the UK, involving cases related to materials failure and thermal degradation in industrial applications. Her first-class degree in Forensic Engineering and Master’s in Steel Technology, along with the Cardiff University Bond Solon Expert Witness Civil Certificate, reinforce her ability to deliver objective, defensible analyses. She is regularly engaged by both plaintiff and defense counsel to provide clear, independent determinations of causation in disputes involving materials failure and degradation.
