When the mathematical theory of plasticity was first introduced to civil engineers in the 1950s under the leadership of William Prager of Brown University, the topic was taught in the applied mathematics department with tensor notations that were hardly readable and understandable for most civil engineers.

We had a rigorous theory but few practical solutions.
