Most labs would most likely use joules as the total amount of energy in collision studies, as usually the are multiple contributing forces acting in concert.
In simulation software such as Solid Works (which I speculate S&W and most Firearms companies are using to perform stress analysis and prototyping) the output is typically a thermodynamic expression.
When I return to my office I will add some technical resource references on internal ballistics and terminal ballistics for those interested at the real science.
