Soils plasticity

Make your own clay. Find an area in your community where the soil is tightly packed and resembles clay. Dig out a ball of this soil. Add just enough water to make the soil plastic. Sculpt your clay into a molecular shape. It might be a bent water molecule or a tetrahedral-shaped methane molecule. Let your molecular model dry in sunlight. Paint your molecular model sculpture.

Many different anchor capacity theories have been developed to determine the vertical anchor capacity. These theories are based on soil plasticity analyses following observations of soil rupture surface geometry in the laboratory or field. Figure 10.42 summarizes some of the failure theories proposed by different researches, which suggest...

A widely respected author. Dr. Chen has authored and coauthored more than 20 engineering books and 500 technical papers. His books include several classical works such as Limit Analysis and Soil Plasticity (Elsevier, 1975), the two-volume Theory of Beam-Columns (McGraw-Hill, 1976 and 1977), Plasticity in Reinforced Concrete (McGraw-Hill, 1982), and the two-volume Constitutive Equations for Engineering Materials (Elsevier, 1994). He currently serves on the editorial boards of more than 15 technical journals. 

The great bulk of soiled plastic films left at the head of the field will soon accumulate to unmanageable quantities, since burning of the material is not allowed in most countries. Moreover, this is not an efficient method as the burning plastic melts, chars and becomes a block of material that will resist all further handling. Transportation to landfills is costly and the lack of landfill facilities generally precludes the burial of the waste material.
