Abstract: The stability of frictional materials that display a nonassociated flow rule is discussed. Particular emphasis is put on an analysis of recent experiments conducted by Lade et al. (1987), where stable behavior was observed, ...

Abstract: A series of biaxial (plane strain) experiments were conducted on three sands under low (15 kPa) and high (100 kPa) confining pressure conditions to investigate the effects of specimen density, confining pressure, and sand ...

Abstract: Digital imaging analysis was used to study localized deformations in granular materials tested under plane strain condition. Two independent techniques were applied and compared. In the first technique, the digitized optical ...

Abstract: A complete set of potential functions consisting of three scalar functions is presented for coupled displacementtemperature equations of motion and heat equation for an arbitrary x3convex domain containing a linear ...

Abstract: A modified form of Wilcox’s low-Reynolds-number k-ω model (Wilcox, 1994) is proposed for predicting recirculating flows. The turbulent diffusion for the specific dissipation rate, ω, is modeled ...
