Mechanical Testing Laboratory - Instructions |
The laboratory is equiped with a Lloyd's Tensile Testing Equipment. The description of the equipment is available here.
On clicking the link "Laboratory Gateway", you will be prompted for a password provided to you (IMPORTANT NOTE: ensure that your browser is java enabled).
Once you enter the lab, you will notice one window which shows a live video of the tensile equipment showing a tensile sample gripped between two jaws (in case this window is not visible double click the streaming video icon). There will be two other icons visible, named: "Console" and "Remote Tensile Test". First double click on the "Console" icon. A small window will pop-up showing come control buttons (if these buttons lit-up then the tensile testing maching is on-line). If the "Console" window shows non-zero displacement then it can be zeroed by clicking the "0" button prior to starting actual tensile test.
Double click the "Remote Tensile Test" icon for conducting the tensile test. A window named "Remote Tensile Test" shows up.
In the "Remote Tensile Test" window click "edit" and then select "Insert New Test" (alternatively "F5" is the keyboard shortcut) for conducting a tensile test. A graph window will pop up on the screen (you may need to resize the window) - there will be two rectangular areas (one area is blank, while the other contains sample dimensions and test parameters). The sample dimensions and test parameters can be modified by double clicking in the rectangular area. After modifying the value click anywhere outside the rectangular area.
To start the test, click the menu item "Test" and then select "Start Test". A "Sample Information" window opens up. In this window you can enter sample-reference or ID and gauge length of the sample. Click "OK" to initiate the test.
As the test is being conducted, a load versus displacement graph appears progressively in the blank window. If necessary use the "Zoom" items under the "Tool" menu to rescale the graph dynamically.
Once the test is completed the test data can be transferred to your computer via the clipboard. Bring the cursor on the graph window and right click. Select "Copy to Clipboard". Now, select the "Clipboard" menu visible on the top of your screen. All the test data will be visible in the "Clipboard". Simply do a copy and paste to your favourite editor or Excel sheel. The data thus saved in your computer can be analysed (details of the analyses can be found in the specific laboratory handouts.
