ffjhl 2009-07-08 18:29 Rev.: 44472

fixed a typo: should be 'use_polar_decomposition_RMB'.
Also changed the default behavior to true after more testing.

3 lines of code changed in 1 file:

• CCA/Components/MPM/ConstitutiveModel: ViscoPlastic.cc (+3 -3)

ffjhl 2009-07-07 01:16 Rev.: 44465

merged previous two versions (due to mistake in commit).

25 lines of code changed in 2 files:

ffjhl 2009-07-07 00:48 Rev.: 44462

added d_usePolarDecompositionRMB as an option (default is false).

added failureByPressure option: the particle will fail if
the allowable mean stress is exceeded (tensile or compressive).
So all together three failure options are available: maximum
principal stress, maximum principal strain and mean stress.

ffjhl 2009-06-13 00:33 Rev.: 44415

added allow_no_tension option for failed particles - only negative
mean stress is retained after failure.

ffjhl 2009-06-11 12:01 Rev.: 44412

added AllowNoShear to the erosion algorithm which
retains only the mean stress (tension and compression)
after failure, i.e., it does not allow deviatoric
stress. Consequently, tension or compression after
failure is treated the same. Note that the existing
AllowNoTension algorithm retains only compressive
mean stress after failure.

1. Added diagnostic output when negative jacobian of deformation
gradient occurs.
2. Per Jim's 2005 modification of ElasticPlastic.cc, reset deformation
gradient of failed particles to previous value to prevent further
straining of these particles.

Using the RMB version of polar decomposition. Note that modifications
for the implicit version are not done yet.

Fixed a bug in radialDirection. tt is not supposed
to be of unit length. Note that axis/height2 is
the axial unit vector; projOnAxis is the projection
of pbot onto axis.

ffjhl 2009-01-01 16:31 Rev.: 42813

added -cyl option so a cylinder can be created inside the given
geometry object. This is done primarily for image data (cropping).
