Consistive Component Of Analysis In Ice Hockey

1709 Words 7 Pages
The resistive component of analysis can also be modeled as a spring in which the spring constant is positively correlated to the force applied to the spring: F= kx, where k = f(x)*Fimpact. The force of impact would mostly dissipate through the springs, and the specific behavior of the springs can be modeled in later stages. The component of force that needs to be looked at primarily is the x component, since this is the component of the force that would produce the most torque on collision. Since the x component of both the spring and the impact forces are relatively more important, this means a system should be created that hinders most of the translational/rotational movement in the x direction.

It is assumed that rotational acceleration experienced by the head causes more concussions than linear acceleration and that football data collected relating to concussions can be applied to ice hockey. Bioband will not be used in extremely low or high temperatures, with the threshold of the material being -196°C to 160°C (Singh, 2013). The area of impact from shoulder-to-jaw collisions is approximately one square …show more content…
When the bullet hits the aramid fiber, the fiber is strong enough to have only a few threads break; this does not allow the force of impact of the bullet to go through the fibers, and thus the energy is spread outward instead of penetrating the fiber itself. For example, an experiment with Kevlar 29 and the bullet NATO 7.62 has shown that the pressure experienced by the vest was approximately 1.8 MPa (Singh, 2013). This is a dramatic reduction of the stress considering that the mean pressure that a NATO 7.62 bullet can apply reaches 385 Mpa (Giglio, 2012). A similar method is applied for the Bioband; the peak positive pressures at the coup site ranged from 53 to 130 kPa for the cases with injury outcome and 40 to 101 kPa for non-injury outcomes. Assuming that the impact area for head-to-shoulder collision is about 1 square inch, and the force from the peak pressure, using the formula (P = F / A), is 84 N, the Bioband dissipates this force without breaking, considering that the chinstrap is approximately 0.1 m wide and 0.15 m long, and the pressure decreases to approximately 5.6 kPa, which is not within the threshold of the shear stress that would result in concussion. To avoid the issue of direct contact between
