Material Property Checks for MAT2

MAT2 only applied to 2D elements.

Material Requirements MAT2
Mathematical None
Semi-stability If any eigenvalues of [G] < 0, an error termination will occur.

PARAM,CHECKMAT, NO will disable this error.

Not all zeros If all eigenvalues of [G] = 0, an error termination will occur.

If any eigenvalue of [G] = 0, a warning is provided.

Consistency none
Mathematical for composites After homogenization, if Det[G] = 0, an error termination will occur.
