The Airy stress eigenfunction expansion of Williams [1] has been used to obtain simple expressions for the angular variations of the stress and displacement fields for n-material wedges and junctions… (More)
Given NASA’s renewed initiative to return to the moon, it is imperative to develop a mobility platform which will enable a wider range of exploration and science. To this end a wheel which can… (More)
Abstract In-plane solutions are given for the order of the stress singularity at an internal point in an elastic, isotropic solid where three wedges of different materials meet. The three interfaces… (More)
A finite element formulation is developed for the analysis of singular stress states at material and geometric discontinuities in anisotropic materials loaded inplane. The displacement field of the… (More)
The plane elasticity problem for two bonded half-planes containing a crack perpendicular to the interface is considered. The primary objective of the paper is to study the effect of very steep… (More)

In this work, we use a combination of first-principles calculations under the density functional theory framework and heat transport simulations using the atomistic Green's function (AGF) method to… (More)
In an effort to build a shear band of a lunar rover wheel which operates at lunar surface temperatures (40 to 400K), the design of a metallic cellular shear band is suggested. Six representative… (More)
Abstract An analytical model for a compliant non-pneumatic tire on frictionless, rigid ground is presented. The tire model consists of a thin flexible annular band and spokes that connect the band to… (More)
