Speech Title: The strain rate intensity factor in plasticity and its application

Abstract: This research is motivated by numerous experimental observations that demonstrate that a narrow layer with drastically modified microstructure is generated near frictional interfaces. This layer is usually called white layer in papers devoted to machining processes and fine grain layer in papers devoted to metal forming processes. Two of the main contributory mechanisms responsible for the generation of such layers are: (a) the mechanism of rapid heating and quenching and (b) the mechanism of intensive plastic deformation. The latter can be described by means of the strain rate intensity factor. This factor is the coefficient of the leading singular term in a series expansion of the equivalent strain rate near maximum friction surfaces. This expansion shows that the equivalent strain rate is infinite at the friction surface. Therefore, the strain rate intensity factor controls the magnitude of the equivalent strain rate in its vicinity. A necessary condition for the existence of the strain rate intensity factor is the friction boundary condition in the form of the maximum friction law. This boundary condition is often adopted at the tool - chip interface (at least, over a portion of this interface) in machining processes. This zone is usually called the sticking zone. The existence of such zones has been reported in deformation processes as well. However, it is worthy of note that the actual seizure (the velocity vector is continuous across the interface) may or may not occur in theoretical solutions. It depends on the constitutive equations chosen. The present paper deals with an approach for using the strain intensity factor in constitutive modeling for predicting the evolution of material properties in a narrow layer in the vicinity of frictional interfaces. The theory developed is supported by experiment on extrusion of a magnesium alloy.

Title of Speech: Automatic topological Synthesis of Mechanisms and Creative Design

Abstract:  In the design of various mechanism-based products, conceiving the mechanisms with better performance has been a challenging issue. For a long time, it has been researchers’ experience and intuition that are mostly relied on in the conception of candidate structures and the selection of one of them for the task. The structural synthesis of mechanisms which can generate a complete list of kinematic chains and mechanisms free from isomorphism and degenerate chains can provide the designers with all the independent candidate kinematic structures of mechanisms of choice. This report focuses on a novel synthesis method which is at the same time effective, automatic and designer-friendly. One can obtain all the valid topological structures of mechanisms and develop the atlas database containing all the topological graphs for these mechanisms with different numbers of links. Based on the classified atlas database, a creative design method is also addressed to generate all the feasible mechanisms for a specified design task.
