How to Use This Tool

This tool allows you to create a ballistic report with energy estimation based on fracture measurements in ballistic gel. Please ensure to complete all mandatory fields.

Measure the following in your ballistic gel block:

Total Wound Path Length (L): The full length of the projectile's path
Cavity Start Point (d): Depth where cavity and radial fractures begin
Cavity Length (c): Length over which cavity and fractures continue
Maximum Cavity Width (w): Widest point of cavity and radial fractures

Note: If the wound does not have a cavity, enter 0 for cavity width and cavity length. Volume will then be cylindrical based on projectile width.

Ballistic Chart with Energy Estimation

Energy Estimation Formula

Volume (V) = cylinder for non-cavity regions + frustum-sum for cavity (if present)

Energy (E) = 3 × Volume

The chart illustrates penetration depths and energy transfer of various projectiles. Each test is represented with its penetration depth as a percentage of block length. The energy transfer is indicated by the color intensity (darker red indicates higher energy).
