Experiments show that this threshold condition is reached within a range of critical thicknesses of the top and bottom elastomeric layers, for a given height of impact of the rigid spherical indenter.
A parametric study of various pedestrian loading conditions was implemented by finite element simulations regarding three influencing factors: impact heights, locations of impact and impact velocities.
After leaving the National, Gillian became part of the Joint Stock Company in the mid-1970s, for an extended period at the height of its impact.
And the sound designer Kristian Eidnes Andersen, who also worked with Mr. von Trier on "Antichrist," uses his understanding of music composition to bring those sounds to the height of emotional impact.

In the first experiment, effects of grain drop height and types of impact surfaces (glass, wood and metal) on SPL were evaluated.
In the repeated impact tests, the effect of impact height on the maximum compressive stress and the damage pattern was evaluated.
Firstly, a high-performance drop hammer setup is employed to carry out the impact tests on five hot-rolled square tubular T-joints with different chord thickness and width ratio of brace/chord under three levels of impact height.
If the sharpest part of the keel is the site of impact (height = ∼0.20 cm), and 1 cm of length is involved, then the area of impact is 0.20 cm2.
For calibration, both the reference accelerometer and the fabricated accelerometer were attached on a rigid metal block and this rail-guided block was dropped from various heights to apply different amount of impact to the accelerometers.
