DESCRIPTION:Problems in soil-machine interaction (SMI) are ubiquitous on E
 arth\, and they are beginning to play important roles\nelsewhere as we exp
 lore off-world applications. While methods to simulate machines have devel
 oped rapidly\,\nmethods for predicting the forces and reactions generated 
 through soil contact are underdeveloped and\ninadequate. General-purpose n
 umerical techniques based on continuum approaches and discrete element met
 hods\nhave advanced to the stage that they can model SMI problems—and in
 deed they are the leading tools used by\nindustry—but these methods suff
 er from significant drawbacks\, particularly with respect to their prohibi
 tive\ninefficiency. Considering several fundamental examples\, this presen
 tation discusses the formulation and validation\nof efficient analytical a
 nd semi-analytical techniques for predicting forces and deformations in SM
 I problems using\ngeneralised bearing capacity theory. These models are sh
 own to be not only accurate but also capable of\nproviding a level of phys
 ical insight that would be difficult if not impossible to achieve using ge
 neral-purpose\nnumerical techniques.\n\nJames (Jim) Hambleton was educated
  at the University of Minnesota\, where he completed three degrees (BCE\,\
 nMS\, and PhD) in Civil Engineering. After several years at the University
  of Newcastle\, Australia\, he became a\nfaculty member in the Department 
 of Civil and Environmental Engineering at Northwestern University in Evans
 ton\,\nIllinois\, USA. Upon relocating to England in late 2023 with his fa
 mily\, he is now an Associate Professor in the\nDepartment of Engineering 
 and a Fellow at Gonville and Caius College at the University of Cambridge.
