"Dewey-Mackenzie estimates." Mackenzie’s solution may be considered a special case of the more general and difficult problem that Dewey set herself and succeeded in solving exactly. As of 2021, her paper has been cited over 130 times in scientific journals. In fact, the approach in her original paper is now so well known that it is often referred to only indirectly, as a "Dewey-Mackenzie estimate," without citation. Slade-Dewey equation While at BRL, one of her contributions to ballistic science has come to be known as the Slade-Dewey equation, which empirically relates the critical impact velocity Vt for initiating detonation of a solid secondary explosive or propellant to the diameter d of an impacting projectile, , where A and B are empirical constants that depend on the explosive.
