Pk. Kar et Ns. Das, UPPER BOUND ANALYSIS OF EXTRUSION OF I-SECTION BARS FROM SQUARE RECTANGULAR BILLETS THROUGH SQUARE DIES/, International journal of mechanical sciences, 39(8), 1997, pp. 925-934
In the present study the SERR technique has been reformulated to deal
with extrusion of sections with/without re-entrant corners. A comprehe
nsive computational model has been developed for this reformulated tec
hnique. The model has been used to analyse extrusion of I-section bars
and the computed results have been compared with experimental values
available in literature. (C) 1997 Elsevier Science Ltd.
