During his work at the
Massachusetts Institute of Technology he developed the
lattice analogy which models membrane and
plate bending of structures as a
lattice framework. While this work received little attention at the time because of the lack of computational power, it is often considered as the turning point in the
Time-Line of the Structural Analysis leading to development of the
Finite Element Method. He later extended the lattice models to plate and shell buckling problems, and made important contributions to the plastic design theory of metal structures. == References ==
