# Shock Load Calculator v1 ## Subject

A shock load is a dynamically applied force that converts kinetic energy into deformation energy in the impacting mass and the impacted body at the time of impact.

If there is no deformation at all in both the impacting mass and the impacted body, the resultant force would be infinite irrespective of the magnitude of the impacting mass and its velocity at the moment of impact. The deformation generated in the mass together with the deformation in the body will define the force of the impact; i.e. the greater the deformation the lower the force and vice-versa.

## Calculator

Shock calculates the energy, deformation, stress, natural frequency, etc. due to a mass travelling at a specified velocity and impacting a beam or plate with various end and edge support conditions or an undefined body.

Shock also includes a general energy conversion calculation similar to that included in CalQlata’s Engineering Principles calculator, inasmuch as you enter all known values and Shock will calculate the unknown.
