摘要： PROBLEM TO BE SOLVED: To provide a method of determining a shear friction coefficient between a cylindrical specimen undergoing friction and an anvil in a compression process for a cylindrical specimen of an optional height/radius ratio based on finite element analysis as to a simulation of a compression process.SOLUTION: Changes in the shape of the cylindrical specimen, that is, the heights (Hand H) of the specimen before and after compression, and an original end-face radius (R) of the specimen after compression and a maximum radius (R) thereof, are put together to derive a relation between a strain and a friction coefficient. In the case where an initial height/radius ratio of the cylindrical specimen is constant, a relational expression is established between a shape change and a friction coefficient after systematically FEM-analyzing a change in the specimen shape caused by friction in the compression process. A change in the specimen shape is systematically analyzed from the height/radius ratio of the cylindrical specimen and a change in the friction coefficient to establish a relational expression among the friction coefficient, an initial specimen height/radius ratio, and a specimen shape. This allows a friction coefficient to be determined in a compression process for a cylindrical specimen of an optional height/radius ratio.

摘要： PROBLEM TO BE SOLVED: To provide a friction correction method in hot working of a columnar sample for correcting stress affected by friction to stress peculiar to a material in the compression process of the columnar sample with an arbitrary height/diameter ratio based on a finite element analysis at simulation in a hot compression process.
SOLUTION: A peculiar stress-strain curve of a material in an assumed simulation process is assumed to be constant to allow the variation of the stress by the friction to be easily examined, and the variation of the stress is calculated by comparison with the stress effected by the friction. When the initial height/diameter ratio of the columnar sample is constant, the stress variation by the friction in the compression process is subjected to systematically FEM analysis and a relational formula of the stress variation and a friction coefficient is formed. The stress variation is systematically analyzed by the variation of the height/diameter ratio and the friction coefficient of the columnar sample. The relational formula of the friction coefficient, the initial sample height/diameter ratio, and the stress variation is formed, and a friction coefficient in the compression process of the columnar sample with the arbitrary height/diameter ratio is decided.
