Uniaxial and triaxial compression test series on the Topopah Spring member from USW G-2, Yucca Mountain, Nevada

Technical Report ·
OSTI ID:60048

Thirty-six uniaxial and triaxial compression experiments were performed on cylindrical samples taken from the Topopah Spring Member of the Paintbrush Tuff from core hole USW G-2 at Yucca Mountain in southern Nevada. Test results are consistent with those for samples of the Topopah Spring Member from other core holes. Decreased strain rate resulted in lower strengths and Young`s moduli, and larger samples were weaker and had higher Young`s moduli. Samples containing preexisting fractures demonstrated little or no linear stress-strain behavior. 9 refs., 107 figs.
