| description | This paper presents the analysis of energy absorbed that produced from an instrumented
charpy impact in order to evaluate the toughness of materials. Alloy rims made from aluminium
6061-T6 are easily damage, fracture and can even destroy after impact loading compared to the
steel rim. For this reason, an idea was initiated to determine the strain signal pattern and strain
energy for evaluting the toughness of materials. Strain gauges were experimentally connected to
the data acquisition system and it was then attached to the charpy striker for the impact signal
collection. Specimens of aluminium alloy of 6061-T6 and carbon steel 1050 were used and its
were designed according to the ASTM E23 standard. In this work, the signal was converted from
the time domain to the frequency domain using the power spectrum density (PSD) method and the
area under its graph was then used to calculate strain energy. The comparison between absorbed
energy and strain energy was performed based on different materials and thicknesses. It was found
the effect of the strain signal pattern with different materials and thicknesses to be influnced the
strain energy. |
