The details of the stress state at the dangerous points.

Stress state	Location of the dangerous points
: the biaxial tensile stress state	The upper points of the central cross-section in samples of GS05, GS10, RS05, and RS10.
: the biaxial compressive stress state	The lower points of the central cross-section in samples of GS05, GS10, RS05, and RS10.
: the uniaxial tensile stress state	The lower points of the edge cross-section in the sample of GS05.
: the uniaxial compressive stress state	The upper points of the edge cross-section in the sample of GS05.
: the pure shear stress state	The neutral points of the central cross-section in samples of GS05, GS10, RS05, and RS10.
