Fragmentation (FRAG)

This is a fragmentation explosion such as the one which would be expected from a HE detonation.  The shape of this explosion is calculated based on the impact angle, explosive velocity, projectile speed at time of detonation, as well as a series of other factors. 

The fragmentation event has a blast component which is generally a smaller radius and results from the explosion of the round itself, and a fragmentation component which is normally larger in radius, has its own fragmentation pattern and is caused by the shell casing fragmentation.

When defining a fragmentation explosion, the following parameters must be defined.

• BLAST_RADIUS: (number) - This is the distance that the central blast of will affect (this is a radial effect).  Units are meters.

• BLAST_FORCE: (number) - The amount of penetrative force that the blast of the detonation will have.  This should be compared against strength of targets where a tank has a penetrative strength of 85, a vehicle has a penetrative strength of about 35 and a person has a penetrative strength of about 8.  The blast force will decay with distance and when it is greater than one of these values, damage will likely be inflicted on that target.

• BLAST_FORCE_HALF_DIST: (number) - This defines how quickly the blast force reduces at distances away from the detonation point.  It is the distance that blast force will be half its original strength.  Therefore smaller values imply that explosion is stronger over a larger area.  Units are meters.

• FRAG_RADIUS: (number) - This is the distance that the fragmentation pattern will affect.  This is will be stretched at parts and squashed in other parts in order to get the correct detonation shape, but this value will be the average radius outside which no damage occurs.  Units are meters.

• FRAG_FORCE: (number) - The amount of penetrative force that the fragmentation of the detonation will have.  This should be compared against strength of targets where a tank has a penetrative strength of 85, a vehicle has a penetrative strength of about 35 and a person has a penetrative strength of about 8.  The fragmentation force will decay with distance and when it is greater than one of these values, damage will likely be inflicted on that target.

• FRAG_FORCE_HALF_DIST: (number) - This defines how quickly the fragmentation force reduces at distances away from the detonation point.  It is the distance that fragmentation force will be half its original strength.  Therefore smaller values imply that fragmentation is stronger over a larger area.  Units are meters.
