The geometric form of ( ) is that of a paraboloid in principal stress space.
2.
Should he ? ( Does having a stress space named after you make you notable ? )"
3.
The yield surface is usually expressed in terms of ( and visualized in ) a three-dimensional Haigh Westergaard stress space.
4.
Functions of the principal stresses, such as the yield function, can be represented by surfaces in "'stress space ".
5.
Any pair of coordinates that differ from ( z, r ) by constant multiples of equal absolute value are also isomorphic with respect to principal stress space.
6.
The term " Haigh-Westergaard space " is ambiguously used in the literature to mean both the Cartesian principal stress space and the cylindrical Lode coordinate space
7.
Figure 2 shows the Tresca Guest yield surface in two-dimensional stress space, it is a cross section of the prism along the \ sigma _ 1, \ sigma _ 2 plane.
8.
To determine the equation of the stress ellipsoid we consider the coordinate axes x _ 1, x _ 2, x _ 3 \, \ ! taken in the directions of the principal axes, i . e ., in a principal stress space.
9.
The Lode coordinate system can be described as a cylindrical coordinate system within principal stress space with a coincident origin and the z-axis parallel to the vector ( \ sigma _ 1, \ sigma _ 2, \ sigma _ 3 ) = ( 1, 1, 1 ).
