ABSTRACT
Abstract New course has been conceived to introduce the problems of high strain rate processes into the curriculum of mechanical engineering students. The emphasis is on the initial structure influence and its changes during the deformation. The course comprises lectures dealing with measurement of dynamical mechanical properties, structure data, and specific characteristics of various processes such as "conventional" high speed forming, explosive hardening, explosive forming etc. Laboratories contain two parts: first, the measurement of dynamic yield stress using Taylor Anvil Test and analysis of experimental results, and second, die structure studies of specimens obtained both in the Laboratory and in the field tests that employ other loading modes (shaped charges, explosive loading etc.) and evaluation of these experimental data. Spall strength is measured on field experiment specimens. Keywords: education, engineering, high strain rate, forming, Taylor test, spall fracture, mechanical properties, structure
1 Introduction
The need is being felt to improve, especially in the fourth and fifth years of engineer education, the courses focused on forming technologies. This improvement observes three objectives: (a) the application of up to date computational methods, (b) development and application of measurement techniques (e.g., measurement of stress variations during the die forming, and (c) allowing die students (and lecturers) to get the "feeling" for material and its structure, to understand the failure under complicated conditions
existing in forming process, to understand die effects of high strain rate. The aim of this contribution is to describe attempts made to fulfil (c).
