Complex, multi-stage models can be easily created and quickly analyzed - tunnels in weak or jointed rock, underground powerhouse caverns, open pit mines and slopes, embankments, MSE stabilized earth structures, and much more. Progressive failure, support interaction and a variety of other problems can be addressed. RS² offers a wide range of support modeling options. Liner elements can be applied in the modeling of shotcrete, concrete, steel set systems, retaining walls, piles, multi-layer composite liners, geotextiles, and more. Liner design tools include support capacity plots, which allow you to determine the safety factor of reinforced liners. Bolt types include end anchored, fully bonded, cable bolts, split sets, and grouted tiebacks. One of the major features of RS² is finite element slope stability analysis using the shear strength reduction method. This option is fully automated and can be used with either Mohr-Coulomb or Hoek-Brown strength parameters. Slope models can be imported or exported between Slide and RS² allowing easy comparison of limit equilibrium and finite element results. RS² includes steady-state, finite element groundwater seepage analysis built right into the program. There is no need to use a separate groundwater program. Pore pressure is determined as well as flow and gradient, based on user defined hydraulic boundary conditions and material conductivity. Pore pressure results are automatically incorporated into the stress analysis. Material models for rock and soil include Mohr-Coulomb, Generalized Hoek-Brown and Cam-Clay. Powerful new analysis features for modeling jointed rock allow you to automatically generate discrete joint or fracture networks according to a variety of statistical models. With new 64-bit and multi-core parallel processing options RS² can solve larger and more complex models in shorter times.

The first edition of the Handbook of Clay Science published in 2006 assembled the scattered literature on the varied and diverse aspects that make up the discipline of clay science. The topics covered range from the fundamental structures (including textures) and properties of clays and clay minerals, through their environmental, health and industrial applications, to their analysis and characterization by modern instrumental techniques. Also included are the clay-microbe interaction, layered double hydroxides, zeolites, cement hydrates, and genesis of clay minerals as well as the history and teaching of clay science. The 2e adds new information from the intervening 6 years and adds some important subjects to make this the most comprehensive and wide-ranging coverage of clay science in one source in the English language. Provides up-to-date, comprehensive information in a single source + Covers applications of clays, as well as the instrumental analytical techniques + Provides a truly multidisciplinary approach to clay science
