Q: There's obviously a huge '80s rock element to the show, but is there also an influence from more theatrical-type rockers like Ozzy Osbourne, Alice Cooper, Marilyn Manson and Rob Zombie?
The end fiction between rock specimen and loading plate is used to simulate the constraint of surrounding rock element to the target rock element [25].
where [P.sup.k.sub.j] is the support reaction force at the jth node of the rock element in the x, y, and z directions, [N.sub.j] is the value of the shape function at the jth node of the element at the segmented point, and [T.sup.k.sub.i] represents the three components of [T.sub.i] in the global coordinate system.
This means that for a rock element subjected to tri-axial stresses, 0x, 0y, 0z, it will be assumed that failure is a function of the second stress invariant function (i.e., [[sigma].sub.x][[sigma].sub.y] + [[sigma].sub.y][[sigma].sub.z] + [[sigma].sub.z][[sigma].sub.x]).
Therefore, the pressure variation could be deemed to be only related to the density and volume variations of the rock element. Consequently, the linear equation of state is adopted to describe the rock mechanical properties, which is very suitable for solving the dynamic problem with small deformation and pressure.
