Book Description
Although it is known that impact compaction tests are not appropriate for granular soils, these tests continue to be widely used. Excessive settlements frequently occur in granular soils where specified field compaction is based on Standard Proctor (ASTM D 698; AASHTO T 99) maximum dry unit weights. A laboratory test program evaluated alternative test methods for granular soil compaction control and showed that a Vibrating Hammer method (similar to British Standard BS 1377:1975, Test 14) has great promise for laboratory compaction of these soils.

Book Description
Manufacture of components from powders frequently requires a compaction step. Modelling of Powder Die Compaction presents a number of case studies that have been developed to test compaction models. It will be bought by researchers involved in developing models of powder compaction as well as by those working in industry, either using powder compaction to make products or using products made by powder compaction.

Book Description
Internal instability occurs when the filtrate under the influence of strong seepage forces accompanies the finer fraction from broadly graded granular soils and induces marked changes in its original particle distributions. The changes in particle size distribution may occasionally render the granular filters ineffective in retaining the protected base soils. A prior assessment of internal instability potential is emphasized through some of the well-accepted constriction and particle size-based criteria. The former criteria are too computationally complex to apply in practice, while the latter require only the particle distribution of a soil and are thus preferred by the practitioners for prompt assessments of internal stability. In this study, gradient-controlled hydraulic tests conducted over a range of variably compacted soils were used to analyze some of the existing criteria, which showed partial success in assessing the current test specimens. Further analysis facilitated a useful revision of a well-accepted criterion, which could then reliably interpret the current test results with enhanced accuracy. Additional experimental data from 15 published filtration studies could further validate the current revision, which incorporates both the particle size distribution and relative density of soils, thus making it more appealing for practitioners. Furthermore, a couple of real-life design examples presented to demonstrate the advantages and implications of the current proposition for practical purposes.

Book Description
The powder forming process is an extremely effective method of manufacturing structural metal components with high-dimensional accuracy on a mass production basis. The process is applicable to nearly all industry sectors. It offers competitive engineering solutions in terms of technical performance and manufacturing costs. For these reasons, powder metallurgy is developing faster than other metal forming technology. Computational Plasticity in Powder Forming Proceses takes a specific look at the application of computer-aided engineering in modern powder forming technologies, with particular attention given to the Finite Element Method (FEM). FEM analysis provides detailed information on conditions within the processed material, which is often more complete than can be obtained even from elaborate physical experiments, and the numerical simulation makes it possible to examine a range of designs, or operating conditions economically. * Describes the mechanical behavior of powder materials using classical and modern constitutive theories.* Devoted to the application of adaptive FEM strategy in the analysis of powder forming processes.* 2D and 3D numerical modeling of powder forming processes are presented, using advanced plasticity models.

Book Description
A "Sonderforschungsbereich" (SFB) is a programme of the "Deutsche For schungsgemeinschaft" to financially support a concentrated research effort of a number of scientists located principally at one University, Research La boratory or a number of these situated in close proximity to one another so that active interaction among individual scientists is easily possible. Such SFB are devoted to a topic, in our case "Deformation and Failure in Metallic and Granular M aterialK' , and financing is based on a peer reviewed proposal for three (now four) years with the intention of several prolongations after evaluation of intermediate progress and continuation reports. An SFB is terminated in general by a formal workshop, in which the state of the art of the achieved results is presented in oral or I and poster communications to which also guests are invited with whom the individual project investigators may have collaborated. Moreover, a research report in book form is produced in which a number of articles from these lectures are selected and collected, which present those research results that withstood a rigorous reviewing pro cess (with generally two or three referees). The theme deformation and failure of materials is presented here in two volumes of the Lecture Notes in Applied and Computational Mechanics by Springer Verlag, and the present volume is devoted to granular and porous continua. The complementary volume (Lecture Notes in Applied and Com putational Mechanics, vol. 10, Eds. K. HUTTER & H.
