The Structural Materials Group provides standard reference materials, calibration and measurement services, property data, and predictive models to help ensure the safety and reliability of the Nation's physical infrastructure (e.g., buildings, pipelines, and bridges). We assist other Government agencies, industry, and universities in assessing material durability under extreme operational and environmental conditions and conduct failure analyses post-mortem. Recently, our efforts have focused on energy infrastructure, particularly the safety of pipelines for distribution of oil and gas and alternative fuels such as hydrogen and ethanol.
