Pellini explosion bulge test / Naval Research Lab brittle fracture work

Second of the three post-WWII brittle-fracture research centers. Pellini at NRL, later came to MIT in retirement.

The other place that was important was the US Naval Research Lab. It was Pellini who did all the work down there, and we'll talk about Pellini at some point. After he finished at the Naval Research Lab, he came to a place called MIT in his retirement from the Navy, and he wrote up all the work he did at the Navy research labs. The third place where they did a lot of important work on brittle fracture was MIT. Morris Cohen and Ben Averbach had projects to look at brittle fracture of steel. So most of what we know about brittle fracture of steels came originally from those three places, as a result of going from riveted to welded ships.
