= Lode coordinates
{wiki=Lode_coordinates}
Lode coordinates are a system used in material science, particularly in the study of plasticity and the behavior of materials under stress. Specifically, Lode coordinates help describe the state of stress in materials through a graphical representation in a triangular coordinate system. In three-dimensional stress space, the Lode parameter is associated with the third invariant of the deviatoric stress tensor, which provides insight into how materials yield and fail under various loading conditions.
