The Drawers

When a Drawer is first opened, the Mesh Drawer will be displayed. The Mesh Drawer displays the finite element mesh, with the elements colored according to their gray value (see Chapter 4). Elements and nodes can be selected in the Mesh Drawer.

The rest of the drawers color the elements according to the local stress and strain. See Section 5.2.3 to interpret and control the color scheme.

The Drawers Stress XX, Stress YY, Stress ZZ, Stress XY, Stress XZ, and Stress YZ display the Cartesian components of the Stress (i.e, the stress in the screen coordinate system.)

The Drawer Stress invariant 1 displays the first invariant (the trace) of the stress, $\sigma_{xx} + \sigma_{yy} + \sigma_{zz}$, which is the pressure. The Drawer Stress invariant 2 displays the second invariant,

\begin{displaymath} \sigma_{xx}\sigma_{zz} + \sigma_{xx}\sigma_{yy} + \sigma_{yy... ...}\sigma_{xy} - \sigma_{xz}\sigma_{xz} - \sigma_{yz}\sigma_{yz} \end{displaymath} (5.1)

The Drawer Stress invariant 3 displays the third invariant, or determinant, of the stress tensor.

The Drawers Stress principal 1, Stress principal 2, and Stress principal 3 display the largest (1), middle (2) and smallest (3) eigenvalues of the stress.

The Drawer Shear Stress draws the invariant shear stress, which is one half the difference between the maximum and minimum eigenvalues of the stress.

Each of the above-mentioned Stress Drawers has a corresponding Strain Drawer.

The Drawer Energy Density draws the elastic energy density.
