A Laboratory Investigation of the Undrained Small Strain Behavior of London Clay
Three different total stress-paths were followed during shearing of the anisotropic consolidated (CAU) tests: compression, extension and a stress-path simulating an element under a plate...
Stress-Strain Behavior of Grouted Hollow Unit Masonry
Experimental results from axial stress-strain tests including post-peak response on hollow unit masonry prisms are compared to those of previous researchers....
The Simulation of Soil-Concrete Interfaces with a Non-local Constitutive Model
This investigation explores a method for predicting deformation in the vicinity of interfaces of dissimilar materials such as concrete and soil. Based upon the basic features of the deformation...
Electrical In Situ Measurements for Predicting Behavior of Soils
A new method is presented for predicting the in situ stress-strain behavior of fine grained soils based upon in situ measurements of its electrical properties. The method involves the...
The Calculation of Ice Forces on Arctic Structures
Results of tests conducted to determine the relationship between uniaxial compressive strength of ice and crushing force are presented. A plot of normalized uniaxial compressive strength...
Triaxial Compression Testing of Ice
An understanding of the confined compressive strength of ice is needed to develop constitutive equations and failure criteria for analytical ice-structure interaction models. Procedures...
Constitutive Equations for Ice as a Damaging Material
Constitutive equations for ice subjected to uniaxial compression are developed based on applications of the theory of continuous damage mechanics. A physical model of ice deformation response...
Sea Ice Indentation Accounting for Strain-Rate Variation
Two levels of ice loading are typically considered in the design of drilling and production platforms for the Arctic. Global ice pressures govern the overall structural geometry and dimensions...
Ice Load Prediction with the Use of a Rate-Dependent Anisotropic Constitutive Law
Man-made structures built in arctic offshore areas are subject to ice loads. Traditional methods for estimating ice loads rely on an indentation factor from rigid-plasticity, an empirical...
Effect of Shallow Trench Construction on Cast Iron Pipelines
This paper summarizes the results of three-dimensional finite element analyses to evaluate the strains and displacements sustained by 4, 6, and 8-in. (100, 150, and 200 mm)-diameter cast...
Stiffness Requirements for HDPE, Profile Wall Pipe
For the past two years the Gulf Oil Corporation has sponsored a research study on profile wall High Density Polyethylene (HDPE) pipe at Texas A & M University. A pipe design computer...
The Relative Strain as a Design Criterion for Buried uPVC Gravity Sewer Pipes
When designing buried plastic sewer pipes, the relative strain caused by deflection of the circular pipe section is of particular interest. The reason for increased interest is the present...
Strains Induced by Combined Loading in Buried Pressurized Fiberglass Pipe
In 1983 Owens Corning Fiberglas and Utah State University collaborated on a study of combined strain behavior of fiberglass pipe to quantify the bending strain reduction as a function...
Stress and Strain Responses of a Soil-Pipe System to Vehicular Traffic
A 16-in. natural gas pipeline near Racine, Wisconsin, had been in service for some 30 years. In 1982 road widening operations on a line parallel with the pipe presented the opportunity...
Field Testing of 84-Inch-Diameter Plastic Pipe
During the summer of 1981, a research project was initiated to monitor strains and deformation in 84-inch diameter RPM (reinforced plastic mortar) pressure pipe. Three 20-foot (6. 1-m)...
Design of Non-Pressure Very Flexible Plastic Pipe
There is considerable debate about the correct structural design procedure to be used for very flexible plastic pipe (VFP) - typically glass-fiber reinforced pipe (GRP), reinforced plastic...
