(i.e. the sum of the
strain components in the x, y and z directions). For plane strain analysis
the out-of-plane (z) strain = 0, therefore the volumetric strain = 
.Contours of strain can be viewed by selecting Volumetric Strain or Maximum Shear Strain from the toolbar list.
Volumetric Strain
In general, volumetric strain = (i.e. the sum of the
strain components in the x, y and z directions). For plane strain analysis
the out-of-plane (z) strain = 0, therefore the volumetric strain = .
Maximum Shear Strain
Maximum shear strain = 
where 
= major principal
strain, and 
= minor principal strain. For plane strain
analysis these correspond to the major and minor in-plane principal
stress directions.
NOTE: strain data is not available if the Analysis Type = Complete Plane Strain.
