Study of Deformation and Defects Occurrence in Advanced Forging Techniques.
Abstract
The report consists of two parts. In the first part, the detailed mechanics of flat-punch indentation into specimens of finite dimensions under plane-strain conditions were obtained, based on the observed flow patterns of commercially pure, hard copper specimens. In the second part, Hill's analysis for compression of a long rectangular strip was modified so that the analysis is applicable to compression of a rectangular block having any length-width ratio. The predictions were compared with experimental results obtained with annealed pure aluminum in terms of load-displacement relationships, changes in specimen geometry, flow lines and grid distortions. Also, a comparison was made for the load-displacement curves by the modified analysis and by the sand-heap analogy. (Author)
