A falling body accelerates because of gravity, but this does not cause a dynamic or "shock" load. The dynamic load is caused when the body stops falling; when it is decelerated by an applied force. This force can come from a rope, or the ground. As the rope begins to store the energy of the falling climber, the load increases.

6 FAQs about [Shock load and energy storage]

What is a shock load?

Shock loads are transient loads of very high amplitude and short duration. Typical events that generate shock loads are impacts and pyrotechnic device activation. Very short shock loads propagate like waves in the structure and get reduced when they cross mechanical interfaces.

How does shock loading affect energy dissipation?

This phenomenon is the energy dissipation and nearly full recovery from the damage created by shock loading to high pressures, even after multiple loading events. This response to shock loading contradicts what is known about shock loading for all other metallic materials. Here, we have studied NC Cu alloys containing 1 and 3 at.%

How does shock compression affect energy storage and heat dissipation?

Energy storage and heat dissipation under shock compression are investigated and the microscopic mechanics are revealed. Total deformation is decomposed into elastic and plastic parts based on the model of four decoupling configurations.

Does plastic strain affect energy storage under shock compression?

As plastic strain accumulated, heat dissipation increased, while energy storage did not necessarily increase. The effect of strain rate on energy storage and dissipation significantly depended on the crystal orientation. This work provides a new insight and unique mechanics for energy storage under shock compression.

How do shock loads affect pyrotechnic device activation?

Typical events that generate shock loads are impacts and pyrotechnic device activation. Very short shock loads propagate like waves in the structure and get reduced when they cross mechanical interfaces. Instead, impact shocks can be reduced by systems that absorb and convert the kinetic energy in heat.
