The projected growth of loess ground deformation obeys the laws of hereditary creep theory. The defining equation in increments of stress is given based on the finite element method and the step method. An algorithm for solving the strain-stress state base of the definition of objectives taking into account the elastoviscoplasticity is suggested. The results of the numerical experiment for a flexible...
With two groups of internal state variables and their correlative intrinsic time, a new constitutive equation for rheologic characteristics of soil was developed based on thermodynamic theory and endochronic theory. Numerical solution of the constitutive equation under axial symmetry condition was obtained by optimization. The new intrinsic constitutive equation does very well in simulating the essential...
In order to obtain rheological properties such as the mechanical property, stress relaxation and creep in the Compression Process of Herbage Materials, based on the compression test platform of herbage materials, the virtual instrument system is constructed by using software Labview and NI data acquisition card. This system can collect compressive force, compressive force of test platform wall and...
The indoor triaxial data indicate that rheological deformation of asphalt concrete is large under complex stress, the proportion of which is about 30% in total measured deformation. In this paper, the incremental model based on rheological heredity theory is applied to study of operation character of Yele asphalt concrete impervious structure, and the rationality of incremental model is verified with...
