Book Description
The present study describes the development of an FE model of tooling during production of a transmission gear. Results of the simulation at the puck/die interface during ejection examine the behavior of friction. Machine component deflections under pressure and areas of wear/binding are also predicted. The tooling was developed and modeled in Abaqus, an FE pre- and post-processor. A metal PM (Powder Metallurgy) puck is simulated from the point at the end of compaction, and then at several positions during ejection. A test setup was designed and built. The apparatus will be used to create iron powder compacts, and experimental results will be used to evaluate future models. Experiments with the new design will enable future studies of friction at the puck/die interface. The current design is for a simple puck and an increase in part geometry complexity is proposed with preliminary design requirements.

Book Description
The past decade has seen an explosive growth of interest in the physics of granular materials. Granular media are comprised of macroscopic objects with internal degrees of freedom. Granular assemblies exhibit phenomena that incorporate the properties of traditional solids, liquids and gases, making it a unique state. In many ways, the granular state is a generalized state of matter. This new volume from the Materials Research Society brings together researchers from many countries and disciplines to assess issues and problems concerned with the collective behavior of granular assemblies as encountered in the context of various applications. In particular, these applications include ceramic science, shock propagation and absorption, design and maintenance of stable natural and artificial structures, processing of pharmaceuticals, and self-assembly processes associated with the synthesis of ultrahigh-density magnetic tapes. The volume should be of value to researchers involved in exploring granular material-based technologies, and is expected to stimulate further research in this arena. Topics include: electromagnetic fields; structural issues; flow behavior; and dynamical problems.

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.
