berea sandstone cycle

Advances in Water Resources

strain cycle, for Berea sandstone, is going to be highly nonlinear. As such, hyperelastic equations are applied for modeling the non-linear be- havior of the solid matrix. Generally, hyperelastic materials are char- acterized by the existence of strain or stored energy potential which is a function of finite strain.

Everything You Need to Know About Sandstone

Aug 14, 2019 · Sandstone is a type of rock made from sediment — a sedimentary rock. The sediment particles are clasts, or pieces, of minerals and fragments of rock, thus sandstone is a clastic sedimentary rock. It is composed mostly of sand particles, which are of medium size; therefore, sandstone is a medium-grained clastic sedimentary rock. More precisely ...

For Berea sandstone this has been observed to be in the range [Taber, 1969; Foster, 1973; Gupta and Trushenski, 1979].
