Chapman Laboratory

Testing Facilities
Large Structural Laboratory
The Chapman Laboratory is a fully equipped structural laboratory, incorporating
a flexible system and "strong floor", loads from several Kilograms to
hundreds of tonnes can be applied to objects up to 50m2.
| Specifications |
Common Usage |
| Area: 24 m x 6 m |
Static and dynamic load application of multiple loads at varying
angles and magnitudes |
| Strong Floor :850kN/bolt |
| Bolt Grid: 1.2m x 1.2m |
| 5 tonne overhead crane |
Small Structural Laboratory
The EngTest Laboratory has a "strong floor" and tensioning bed and
is used for general testing.
| Specifications |
Common Usage |
| Area: 15m x 8m |
General low capacity testing |
| Strong Floor: 70kN/bolt |
| Bolt Grid: 1ft x 1ft |
| 2 tonne overhead crane |
Instron Dynamic Testing Machine
EngTest maintains two testing frames and one system comprising of three independent
hydraulic rams. The two test frames are suitable for the testing of components
up to approximately 1m3 in size while the independent rams in conjunction with
the strong floor allow much larger objects to be tested. The frequency response
of all systems is dependent on the item under test.

George Sved Laboratory
This laboratory has several smaller test machines such as the Mohr & Federhaff
universal test machines. These machines are fitted with computer acquisition systems
for recording load and deflection data.
One of these machines is NATA calibrated.
