Stereolithography
Stereolithography is a three-dimensional printing process which produces accurate copies of CAD solid or surface models directly from CAD data. The process uses a moving laser beam, directed...

Polyhedral Substitute Yield Conditions in Plastic Reliability Analysis
The method of invariant linear combinations of linearly associated lower bound safety margins is used for constructing upper bound approximations of the generalized reliability index with...
Upper-Bound Estimate of the Reliability of Plastic Slabs
This paper gives a brief presentation of some recent results on probabilistic analysis of plastic slabs, especially reinforced concrete slabs. The estimate of the reliability of such slabs...
An Investigation of Field Performance of Reinforced Plastic Mortar Pipes
Every year many new pipe materials appear on the market for various applications. One of the important factors the design engineer and the user should consider while evaluating new products...
Pipeline Rehabilitation with Polyolefin Pipe
This paper provides an introductory discussion on the rehabilitation of a deteriorated pipe structure by insertion renewal with continuous lengths of polyolefin pipe. This sliplining or...
Ultrasonic Flow Meter Testing
Six ultrasonic flow meters were tested in a hydraulics laboratory. Accuracies better than 2% were obtained with two transit-time meters on 14 inch diameter steel tubing. Poorer accuracies...
Drag Characteristics of Spheres in Bingham Fluids
R.W. Ansley and T.N. Smith's type of drag relation can be traced back closely, if not completely, to the Newtonian drag curve. The equivalent diameter for a sphere in a Bingham...

Analysis of Plastic Soil in Contact with Cavitose Bedrock
A numerical analysis has been conducted to evaluate the stress deformational response of highly plastic soils in contact with cavitose Bedrock. The numerical idealization represents the...
Plastic Concrete Cutoff Walls
The studies revealed that plastic concrete can be prepared having a coefficient of hydraulic conductivity that is less than 1 multiplied by 10** minus **7 cm/sec. The shear strength of...
