The color-coded P-I diagram consists of three injury contour levels which provide the user with a clear picture of the three zones of structural or human response:

  • Total destruction / fatality zone - 100%
  • Partial damage / injury zone - 50%
  • No damage / injury zone - 0%

If the magnitudes of the pressure and impulse that the structural component must be designed to withstand are known, then the input parameters in BREEZE VASDIP can be varied to generate a series of P-I diagrams. By doing this, the design of the component can be optimized to withstand specified pressures and impulses with respect to one or more parameters.
