In this paper the application of a crystal plasticity model for body centered cubic crystals in the simulation of an sheet metal forming process is discussed.The material model parameters are identified by a combination of a texture approximation procedure and a conventional parameter identification scheme.In the application of a cup drawing process the model shows an improvement of the strain and earing prediction as well as the qualitative spring back results in comparison with a conventional phenomenological model

Electromagnetism for Electronic Engineers
Saturday, August 15th, 2009Description:
Electromagnetism is fundamental to the whole of electrical and electronic engineering. It provides the basis for understanding the uses of electricity and for the design of the whole spectrum of devices from the largest turbo-alternators to the smallest microcircuits. This book starts with conventional sequence of presentation, beginning with electrostatics, then moving to current electricity, the magnetic effects of currents, electromagnetic induction and electromagnetic waves.
