42Mohr-Coulomb theory — is a mathematical model (see yield surface) describing the response of a material such as rubble piles or concrete to shear stress as well as normal stress. Most of the classical engineering materials somehow follow this rule in at least a… …
43Rolling resistance — Figure 1  Hard wheel rolling on and deforming a soft surface, resulting in the reaction force from the surface having a component that opposes the motion. Rolling resistance, sometimes called rolling friction or rolling drag, is the… …
44Hydraulic head — is a specific measurement of water pressure or total energy per unit weight above a geodetic datum. It is usually measured as a water surface elevation, expressed in units of length, but represents the energy at the entrance (or bottom) of a… …

46Formation and evolution of the Solar System — Artist s conception of a protoplanetary disk The formation and evolution of the Solar System is estimated to have begun 4.568 billion years ago with the gravitational collapse of a small part of a giant molecular cloud …
47Slickenside — [ 400px|thumb|right|Slickensides developed on the surface of a small fault in quartzite in the Alpujarras] In pedology, the study of soils in their natural environments, a slickenside is a surface of the cracks produced in soils containing a high …
48Dissipative particle dynamics — (DPD) is a stochastic simulation technique for simulating the dynamic and rheological properties of simple and complex fluids. It was initially devised by Hoogerbrugge and Koelman [1][2] to avoid the lattice artifacts of the so called lattice gas …
