Device Description’ The device has two brass arms fitted perpendicular to each other. The upper part has five holes, one for the loading piston and four for the low friction guide posts, and through which the upper plate moves. A little control over the rotation of the upper platen is provided by the presence of an alignment bar and cam rollers, but careful alignment of the loading system is still required.

Final Report Chapter: Do you enjoy reading reports from the Academies online for free? Two slots are provided in each side wall of He lower platen to help mount the extensometers on to the specimen.
For Me purpose of this analysis, horizontal tensile deformation is considered positive, while vertical compressive deformation is considered negative.
These were fixed to the base of the side walls of the lower platens with a rotating arm on the top which held the EVDTs. The loading system is connected to the device with a complex arrangement using a metal ball and springs between two flanges Figure Ado. However, it should be ensured ved the loading system is perfectly aligned to minimize rocking.
Horizontal – site deformation is considerM to be positive, while vertical compressive deformation is considered to be negative for this analysis.
Holes are drilled in these columns so that the deformations can be obtained by use of EVDTs mounted through them. The Baladi device used in vet study was supplied by the Gilson Company, Inc. This alignment system and its installation is described here. Rotate the specimen so Mat Me first diametral axis coincides completely wig Me etched line on Me plexi- glass window.
This marking device, along wig lines etched on the center of Me loading strips, helps in reducing rocking and making the alignment of Me specimen much easier. The plexi-glass window can be rotated in the horizontal plane and locked in one the front plate. A high degree of freedom exists in the Retsina device, and hence it is more liable to equipment and operator errors. Assume Poisson’s ratio, m for example, assume 0.
The report included the Fund Position statement for quarter 1 1 April to 30 June Motion to exclude the Press and Public That under Section A of the Local Government Act the press and public be excluded from the meeting for the following business on the grounds that it involves the likely disclosure of exempt information as defined in paragraph 3 of part 1 of Schedule 12A of the Act.
The metal plates can be slid over these rods so as to adjust to any Sickness of the specimen. Absolute values of all deformations are to be taken for He purpose of Ads analyses.
The following equations were developed for Me strains along the tic and y axes from the stress equations given by Hondros [A The next meeting of the Committee will be held on Friday 4 November at It is small and simple enough to be used in many small environmental chambers.

Applying heat from a blower accelerates curing. Otherwise, the values of pr and mr were calculatM from the total recoverable 6335. Full details of this proposal would be available later in the day.
Support legs can be slid over the four ends of the brass arms to support the alignment device in place over the specimen while the glue sets. References Page Share Cite. ,s deformations are measured by extensometer assemblies supplied by MTS. A counterweight system prevents the heavy weight of the loading system from being applied to the specimen which is very critical at high temperatures.
