Tutorial 1 (Creating And Running A Simple Test) - Mecmesin MultiTest-x Series Operating Instructions Manual

test programs will be developed, then refined into more sophisticated procedures for
testing and analysis.
Three programs will be developed:
1) A very simple dual segment tensile testing program. No test specimen will be
required, but a loadcell with a capacity of at least 50N is recommended.
2) A monotonic compression testing program. An empty plastic bottle (i.e. a 2
litre PET bottle used originally to contain 'fizzy' drink) and a loadcell with a
capacity of at least 500N will be required.
3) A cyclic program. A tennis ball and a loadcell with a capacity of at least 500N
will be required.
Every step in Tutorial 1 will be described in much greater detail than in the other
tutorials. It is recommended that every new user should work through Tutorial 1.
Tutorial 1 (Creating and Running a Simple Test)
The simple test which will be developed is typical a group of tests where load would
increase from zero, pass through a peak load, then settles down to a fairly steady
load reading which will be maintained for a certain time or displacement. Peeling an
adhesive bond, tearing a sheet of paper, driving a needle through a membrane, or
cutting cheese with a wire would give test results this of this generic form. Typically
the pass/fail assessment carried out after this type of test would check the following:
•
What was the average load?
•
What was the maximum load?
•
What was the minimum load?
The requirements for a specimen to 'pass' could be, for example, that:
•
The average load should be between 18N and 22N
•
The maximum load observed should be between 20N and 25N
•
The minimum load observed should be between15N and 20N
Before starting to set up the test procedure, check that:
