This paper has been prepared in memory of Professor Scott Sloan. It first presents a brief review the development shakedown analysis methods for pavement and railway engineering problems. In particular, it describes new lower-bound method using concept critical residual stress fields an upper-bound nonlinear programming technique, which were developed by authors, then extended applied to solve ...

The plane elastic problem of a circular disk shrink fitted into hole in an elastically similar plane, with frictional interface, is studied subject to the application radial force and torque both which vary time. This done by use edge dislocation distributions represent slip. evolution extent position slip zone as well magnitude displacements studied. Conditions for continuous slip, leading his...

This paper presents a computational homogenization shakedown analysis of periodic perforated materials with von Mises matrices. The plastic behaviors the under cyclic macroscopic loads are studied by means kinematic theorem and method. micro-fields approximated edge-based smoothed finite element resulting large-scale optimization problem is efficiently solved using conic solver, enabling large ...

An early deployment of the xNTD could see 6 dishes with full focal plane array capability installed at the Mileura site by the end of 2008. The system would have a factor 4-5 less collecting area than the complete xNTD with resultant lower sensitivity by a factor of ∼20. I show here that unique H I science can be done with the early deployment instrument. For example, in excess of 1000 galaxies...
