Abstract

The purpose of this data is to investigate the effect of different thicknesses of different soft materials samples added to an object on the resultant head acceleration of a developed dummy head upon impact. The object was a cylinder (10 × 10 cm2, diameter and height) and weighs 0.4 kg. The investigated materials were Ecoflex, Dragon Skin, and Clay while the thickness were 1 mm, 2 mm, 3 mm, and 5 mm. The velocities of the impacts for the 108 experiments were between 1 m/s and 3 m/s. Three severity indices (i.e. peak head linear acceleration, 3 ms criterion and the Head Injury Criterion (HIC)) were calculated from the raw acceleration data. The impact velocities were tabulated from the video recordings. A summary of the processed data and the raw data are included in this dataset.

The data could be used to investigate the potential of soft materials in reducing any harm to the head

Summary

Experimental setup

The experimental setup was based on a low-cost developed dummy head. The dummy head was 3D-printed that was made of polylactide (PLA). Clay was added to make the dummy head reach a mass of 3.1 kg, which is very close to that of children's dummy heads. The accelerations of the head were measured with a tri-axial accelerometer embedded inside the head. This head model was placed in a dedicated frame with ropes (Fig. 1). The readings of the sensor were read at 20 kHz through a data acquisition card. Our earlier studies provided more detailed overview of the experimental setup [2,3]
