Hsu plot — hsu_plot • structr

3D strain diagram using the Hsu (1965) method to display the natural octahedral strain (Nádai, 1950) and Lode's parameter (Lode, 1926).

Usage

hsu_plot(R_XY, R_YZ, main = "Hsu diagram", es.max = NULL, ...)

Arguments

R_XY: ratio of maximum strain and intermediate strain
R_YZ: ratio of intermediate strain and minimum strain
main: character. The main title (on top).
es.max: maximum strain for scaling.
...: plotting arguments passed to graphics::points()

Value

plot and when stored as an object, the Lode parameter Lode and the natural octahedral strain es.
