Total Absorbed Energy (Impact)

The amount of energy that the specimen absorbed during the entire impact test – from start to end. This value may be the same as energy to maximum load when the specimen abruptly fails at the maximum load point. The value is calculated from the time the load begins to rise until the first occurrence of 0 load after the maximum point. This value can be used as an indicator to a materials ductility or toughness – the higher the value the stronger the material. However, are needs to be taken to ensure that when the data collection ends, the load has fallen below the 0 threshold. If it hasn’t, this value is no longer a valid number to be used.
