Strain measures of solid elements

Like stress, strain values reported for solids are at the centroid of the element. Log (true) strain is written to the output only if STRFLG=1 in *DATABASE_EXTENT_BINARY. To plot the true strain in LS-PrePost:

Fcomp > Strain
History > Element

There are other strain measures which are calculated by LS-PrePost from the nodal coordinate data in D3PLOT. These measures are:

infinitesimal strain (Fcomp > Infin)
Green strain (Fcomp > Green)
Almansi strain (Fcomp > Almansi)

After fringing any of the 3 preceding strain measures, you can plot time histories by clicking in LS-PrePost:

History > Scalar.
