EllipAxes {RockFab} | R Documentation |
Calculate ellipsoid axial lengths based on octahedral shear strain and Lode parameter.
Description
Function uses the octahedral shear strain and Lode parameter of a desired strain ellipsoid and returns the normalized axial lengths X Y and Z.
Usage
EllipAxes(es, nu)
Arguments
es |
Octahedral shear strain. Values must be positive. |
nu |
Lode parameter. Values must be between -1 and 1. |
Value
A numeric vector of length three with values returned in descending order (i.e. X, Y, and Z)
Note
Not used in RockFab scripts but can be useful for other endeavors.
