Compute stress, based on lethality index

The model used for this is the logistic model, fitting observed injury/lethality statistics to the base-10 logarithm of the maximum compression stress during a simulated impact event.

Usage

stressFromLethalityIndex(injury)

Arguments

injury

numerical value or vector, giving threat of injury (in range 0 to 1).

Value

whale compression stress, in Pascals.
