A detailed analysis is performed of the plastic deformation in a metal substrate fretted by a ̄atbottomed circular peg under steady normal load and cyclic tangential load. The substrate is coated with a thin layer of soft metal. Two limiting asymptotic problems are identi®ed which characterize small scale yielding behavior in the substrate in the vicinity of the corners of the peg. Deformation ...
The structural reliability with respect to plastic collapse or to inadaptation is formulated on the basis of the lower bound limit and shakedown theorems. A direct definition of the limit state function is achieved which permits the use of the highly effective first order reliability methods (FORM) is achieved. The theorems are implemented into a general purpose FEM program in a way capable of ...
