. From 1955 until his retirement in 1995, he was on the faculty in the Division of Engineering and Applied Sciences at Harvard University, as the Gordon McKay Professor of Structural Mechanics from 1961 and then as the Abbott and James Lawrence Professor of Engineering from 1983.

Some of the underlying ideas in the thesis had emerged from interactions at NACA with Sam Batdorf, whom Bernie came to regard as his most important mentor. Motivation for the new slip theory came from an extensive series of plastic buckling experiments on plates and shells at Langley and elsewhere that revealed that predictions from the so-called deformation theory of plasticity (in reality, not a plasticity model but a nonlinear elasticity material model)

The couple shared many interests, such as literature, good food, travel, and even horse racing. In 1955 Bernie accepted a position as associate professor of structural mechanics at Harvard University, where he soon assumed the Gordon McKay Professorship in Structural Mechanics.

In the early 1960s there were numerous competing sets of shell theory equations creating considerable confusion for engineering users. Koiter made a major breakthrough by showing that errors inherent to any two-dimensional theory of shells meant that many of the competing theories were equivalent as far as accuracy was concerned.

Many other contributions to what became known as micromechanics followed, including the role of fiber debonding and sliding in the tensile fracture of fiber-reinforced composites, fiber kinking as a mechanism for limiting the compressive strength of composite materials, phase transformations as a toughening mechanism in ceramics, and the mechanics of void growth in ductile fracture. For more than 20 years beginning around 1970, Bernie was a member of a Defense Advanced Research Projects Agency (DARPA)

and the Danish Center for Applied Mathematics and Mechanics. Bernie Budiansky will be remembered by colleagues and students as an exceptionally incisive and creative engineering scientist who was always open to discussion and who relished resolving a technical matter.
