Viscoelastic Shrinkage Stress in Soil-Cement Base
Engineers generally consider cracking in soil-cement bases to be caused by stresses induced by shrinkage and ambient temperature. When the shrinkage is assumed to be proportional to the...

The analysis of a three-layer linear viscoelastic half-space under a uniformly distributed circular load is presented. Such an analysis is an essential step in the development of a rational...

Viscoleastic Layered System Subject to Moving Loads
A layered system composed of a linear viscoelastic layer and linear elastic supporting foundation is considered—the layer being described by a classical thin plate and the foundation as...

A semi-empirical method is presented which permits the prediction of the entrance length and entrance pressure drop of laminar flow of non-Newtonian viscoelastic fluid into the entrance...

Analysis of Consolidation by Rate Process Theory
The time-deformation behavior in one-dimensional consolidation tests is analyzed by considering the soil structure resistance as a visco-elastic system. The viscous flow is assumed to...

Vibration of a Viscoelastic Timoshenko Beam
Coupled equations for vibrations of a linear viscoelastic Timoshenko beam of an incompressible material are obtained by replacing the elastic moduli by viscoelastic operators. Time-variables...

Viscoelastic Wave Interaction with Cylindrical Cavity
Stresses at a free-field point and on the boundary of a circular hole in a viscoelastic plate subjected to air shock loading were determined by photoviscoelastic and moiré methods. The...

Interaction of Continuous Frames and Soil Media
A solution to the response of fully continuous orthogonal space frames supported on a viscoelastic soil media is presented. Matrix expressions containing slope-deflection equilibrium equations...

Dynamic Response of Beam on Viscoelastic Subgrade
Initial elasticity and restricted viscous flow of a subgrade greatly influence the dynamic response of a Bernoulli-Euler beam supported by such a subgrade. The beam is of infinite length...

Analysis of a Two-Layer Viscoelastic System
The theory of stresses and displacements in a two-layer linear viscoelastic medium is defined for quasi-static loading, full continuity at the layer interface, and variable material compressibility....

On a Kind of Hysteretic Damping
Slightly nonlinear materials and structures with purely hysteretic damping, subjected to harmonic disturbances, are examined. It is shown that a load-deformation or stress-strain relation,...

Dynamic Response Functions
Visco-elastic, shear, and rotatory inertia effects are introduced into the Laplace transforms of the response functions for lattice structures. The response functions are written in a...
