INVESTIGATION OF THE NATURE OF STRUCTURAL DAMAGE IN METAL-FORMING PROCESSES.
Abstract
Progress is reported on an investigation to acquire an understanding of the way in which hydrostatic stresses influence the initiation and propagation of failure in materials to be able to relate the degree of damage in a particular material to the amount of deformation under a particular state of stress, to categorize materials as to their sussceptibility to damage under a particular set of processing conditions, and to predict for any process those conditions which will lead to the development of the most favorable states of hydrostatic stress and which will produce the minimum amount of damage to the material being processed. Work has been performed in the following areas: (1) Development of high-pressure fluid facilities; (2) Development of high precision density measuring facilities; (3) Ambient pressure sheet drawing; (4) Lubrication and die friction studies.
