relative_stress: Relative principal stress magnitudes and directions

In abarbour/stress: Tools for Working with Stresses and Focal-mechanism Inversions

Description

This function finds the principal stresses from the eigenvalues and eigenvectors of the deviatoric stress tensor, s, defined as the stress tensor minus the mean (or volumetric) stress.

Usage

relative_stress(x, ...)

.deviatoric_tensor(s, ...)

## S3 method for class 'msatsi_slboot_tensor'
relative_stress(x, ...)

Arguments

x	object to extract relative stress magnitudes from
...	additional parameters to .deviatoric_tensor
s	numeric; a vector of stress tensor components in the following order: s11 s12 s13 s22 s23 s33

Details

Uses eigen to return the orientation and magnitudes (in MPa – check this) of the relative principal stresses.
