Produktinformationen zu „Physical Soil Mechanics “
Soil is matter in its own right. Its nature can be captured by means of monotonous, cyclic and strange attractors. Thus material properties are defined by the asymptotic response of sand- and clay-like samples to imposed deformations and stresses. This serves to validate and calibrate elastoplastic and hypoplastic relations with comparative plots. Extensions capture thermal and seismic activations, limitations occur due to localizations and skeleton decay.Attractors in the large characterize boundary value problems from model tests via geotechnical operations up to tectonic evolutions. Validations of hypoplastic calculations are shown with many examples, possible further applications are indicated in detail. This approach is energetically justified and limited by critical points where the otherwise legitimate continuity gets lost by localization and decay. You will be fascinated by the fourth element although or just as it is so manifold.

Soil is a matter of its own right. Nevertheless the properties should be modeled as accurate and reliable as possible. Geoscientists and geotechnical engineers need to rely on models while describing the properties of soil for engineering purposes.
Gerd Gudehus follows accepted principles of natural philosophy and engineering. Soils are complex matter with respect to composition, state an behaviour. This part of complexity can be mastered by means of state limits and limit cycles. Graphical representation helps to lighten the constitutive relations.
The author presents constitutive concepts of elastoplasticity and hypoplasticity. The first part of the book deals with constitutive relations. For sand-like soils (psammoids), state limits are introduced, described as attractors, constitutive relations represented by means of related strain and state paths, validated by means of oedeometer, triaxial, cuboidal, simple shear and torsion shear results. The second part deals with boundary value problems for soils which are no more homogeneous with respect to state and composition.
The concept of related evolutions of state and shape works throughout more complex boundary value problems. It is a powerful tool which will be useful for the description of soils and their properties. Although validated in many cases, the search for improvements will still go on.

Autoren-Porträt von Gerd Gudehus
Gerd Gudehus studied civil engineering in Berlin, where he also completed his doctoral thesis in soil mechanics. In 1973, he became full professor and chairman of the Department of Soil Mechanics and Foundation Engineering at the Institute of Soil and Rock Mechanics, Karlsruhe University. He is head of the Soil Mechanics Section of the German National Geotechnical Society and is engaged in the conservation and restoration of historical retaining walls and in the stabilization of the foundations of historical buildings situated on soft ground.
