EPPL,EQV or EPCR,EQV). For total strains (item and component EPTOT,EQV), you would typically

use an effective Poisson's ratio between the input Poisson's ratio and 0.5. As an alternative, you

can save the equivalent elastic strains using ETABLE with the effective Poisson's ratio equal to

the input Poisson's ratio and save the equivalent plastic strains in another table using 0.5 as the

effective Poisson's ratio, then combine the two table entries using SADD to obtain the total

equivalent strain.

• Effect of /EFACET:You may see different plots with different /EFACET settings when viewing continuous
  contour plots (PLNSOL). If you set /EFACET,1, the contour values for the intermediate locations are
  interpolated based on the average of the adjacent averaged corner node values. However, if you set
  /EFACET,2, the midside node values are first calculated within each element, based on the average
  of the adjacent unaveraged corner node values. The midside node values are then averaged together
  for a PLNSOL contour plot. If you issue /EFACET,4, the program uses shape functions to calculate
  results values at three subgrid points along each element edge. The subgrid values are first calculated
  within each element and are then averaged together for PLNSOL plots. Therefore, the contour values
  at the midside locations will differ with different /EFACET settings.

In most cases,PLESOL contours will be the same regardless of /EFACET settings. However, you

will see differences in PLESOL contour plots if you change /EFACET settings in conjunction with

any RSYS setting other than KCN = 0.When a coordinate system other than global Cartesian is

chosen (KCN = 1, 2, etc.), the results are first averaged in the global Cartesian coordinate system,

and then the averaged results are transformed to the specified results coordinate system.

7.2.1.2. Deformed Shape Displays

You can use these in a structural analysis to see how the structure has deformed under the applied
loads. To generat e a deformed shape display, use one of the following:
Command(s):PLDISP
GUI: Utility Menu> Plot> Results> Deformed Shape
Main Menu> General Postproc> Plot Results> Deformed Shape

For example, you might issue the following PLDISP command:

PLDISP,1! Deformed shape superimposed over undeformed shape
