John Rudnicki, an American engineer, died October 5, 2026, aged 75.
Born in Huntington, West Virginia, he began studying at Brown University in 1969, earning a bachelor’s degree in 1973, a master’s degree in 1974 and a doctorate in solid-state mechanics in 1977. James R.
Rice supervised his doctoral work. Rudnicki later worked at the California Institute of Technology as a postdoctoral researcher and lecturer in geophysics. His research focused on the inelastic behavior and failure of geomaterials, especially deformation instabilities in brittle rocks and granular media. He also studied how pore fluids interact with these materials and their deformation. The applications of his work included fault instability, quantifying energy radiation from earthquakes, and geomechanics related to environmental and resource concerns. These interests brought together the mechanics of earth materials and questions relevant to both geophysical processes and engineering. His professional activities included university teaching and research; Northwestern University is listed as his employer. He received the Drucker Medal. Across these roles, his work was grounded in mechanics, extending from the study of material behavior to problems involving faults, earthquakes and geologic resources.
