摘要:

AbstractThe Green's functions for a set of fully coupled linear equations governing thermal consolidation of a homogeneous isotropic material are presented. The Green's functions are evaluated for one, two and three spatial dimensions, and in the Laplace and real‐time domains. The Green's functions are employed in a boundary integral analysis of a simple problem to demonstrate the influence of full coupling on the field quantitie

摘要:

AbstractElastic–plastic deformations in pavements consisting of layers of different frictional materials are investigated. The upper bound, kinematic shakedown theorem is used to obtain estimates of the critical shakedown loads. Fully general three‐dimensional deformations are considered. The influence of the loading distribution, interactions between loads, and the effect of varying the thickness, stiffness and strength of the layers are explored. Consequences of this investigation for particular existing designs of flexible pavements are investigated. In particular, it is found that the strength of the subgrade has no effect on the magnitude of the critical shakedown l

摘要:

AbstractNumerical results of the simulations of the saturated clay response to a line heat source with a constant power output are presented and compared to the analytical solutions. Mixture theory of two interacting thermoelastic constituents is employed for the modelling. In this theory, mass transfer between the adsorbed water and bulk water is included to simulate the degeneration of adsorbed water into bulk water occurring at elevated temperatures. A finite difference method with non‐uniform mesh is adopted to determine both the near‐ and far‐field behaviour. The degeneration of adsorbed water into bulk water is more pronounced close to the heat source. This may produce a lower excess pore water pressure, a higher permeability increase, and accelerate the water flow in the vicinity of the heat s
