~de medição de tensões de trefilação. Com.o uso desse dispositivo foram levantados dados experimentais em função da velocidade de trefilação. Os resultados obtidos foram analisados comparativamente com as previsões teóricas dos modelos adotados em função do coeficiente de atrito, trabalho redundante e dos dados do limite de escoamento e coeficiente de encruamento obtidos do ensaio de tração, de modo a se verificar o distanciamento teórico-experimental

Abstract: The present work had as fts main objective a comparative study of experimental drawing stresses and those predicted from theoretical models, as a function of drawing speed. At first, an extensive bibliographical review was made of the principal
theoretical models for determination of drawing stresses. Afterwards,an apparatus 'for measuring drawing stresses was
Idesigned and built. The' experimental results obtained were then compared with thos~ expected from theoretical models as a
function of the friction coefficient, the redundant work and the data concerning yield li~it and strain hardening coefficie~t,
