Elastic/plastic deformations in frictional materials under moving surface loads are investigated. The static and kinematic shakedown theorems are used to obtain estimates of the critical shakedown load for plane strain deformations under trapezoidal surface load distributions and for three‐dimensional deformations under loads distributed over circular areas. It is shown that the material can fail either by incremental collapse or in cyclic or alternating collapse modes.
