Qualifying very thick steel and new steels for use in construction, shipbuilding, pipes, and heavy equipment is not easy. Charpy tests are usually used, but the resulting data is not always consistent. Bill Mohr, EWI Principal Engineer for Structural Integrity, has conducted a study of crack specimens with splits. His work shows that Charpy and...

The energy economy is experiencing a shift away from oil and gas sources as European nations and states, such as California, impose legislation on utilization and sourcing. A primary, would-be displacer of natural gas in the utility space is hydrogen (or chem + hydrogen hybrid fuels). In most cases, the preference of industry would be...

Polymer properties can permanently change as they age, which can lead to unexpected failures. These failures can be avoided by considering the polymer’s response to the environment during early product design. Liquids, gases, heat, and irradiation can have irreversible chemical effects on a polymer. Alternatively, in some cases the polymer can affect the liquid’s properties....
