| description | Aluminium is a well-known material in the modern era with its high cost-performance ratio
and exceptional material properties making it advantageous for applications in the
aerospace and automotive industry as well as other industries. Although its aluminium data
can be found online easily, its strain rate dependent data is difficult to find. To research and
better understand the material behaviour under high strain rate conditions, the compressive
Split Hopkinson Pressure bar (SHPB) technique is used in this project. The test is suitable
for high strain rate testing with ranges from 102 to 104 s-1
.
Before experiment testing, equipment such as strain gauges, pressure bars, strain meter &
oscilloscope must be properly set up and calibrated. For enhanced accuracy, specimens
must be machined and polished with precise dimensions. During the compressive SHPB
experiment, strain gauges detect the impact and send signals which are received by
oscilloscope and converted into data for analysis of stress, strain, and strain rate. After dry
run tests, key parameters such as impact velocity, wave velocity and average strains were
analysed. Comparison with past reports’ data, repeatability tests and calibrations were done
to ensure accurate and consistent results of aluminium, Al6061-T6, are being recorded. |
