THE CALCULATION OF ROLLING PRESSURE OF BLOOMING MILL BY THE GENERALIZED VARIATIONAL PRINCIPLE OF IIMIT ANALYSIS

In applying the generalized variational principle of limit analysis in solid mechanics proposed by Reference 5, a simple formula (28) of rolling pressure of blooming mill is derived far practical use in rolling engineering.Comparison with the experimental data obtained in this country shows that the agreement seems to be quite satisfactory, the resuits being more accurate than those from many foreign formulas, and the calculation very straightfotward.
