The Theoretical Principles of Sheet Metal Forming Processes Intensification Based on Anisotropy

Abstract:

Anisotropy of properties is known to be a fundamental material characteristic, which stems from its crystal structure and texturing under plastic deformation. The influence of an anisotropy on the processing and service characteristics of products can be not only negative, but also positive. In this article in order to efficiently use anisotropy of properties in metal forming processes it is described a variation of anisotropic medium plasticity theory with reference to material deformation characteristic and it is analyzed the effect, produced by anisotropy on material behavior in different technological operations (drawing, bending, stretch-forming, etc.). As a result, intensification of deformation processes, increase of production efficiency and improvement of product quality and serviceability become possible.
