Sažetak
Based on the results of studying a joint solution of the Karman equation using a new model of friction stresses, the dependences of the stress state coefficient nσhave been constructed in the range of the parameter l/hav from 4 to 100, which corresponds to the conditions of rolling thin and ultralight gage strips. As a result of approximation of the obtained dependencies, an updated mathematical model of the stress state coefficient has been proposed. Model (1) is valid for fl /hav≤2, 25–2, 40 and is recommended for the calculation of the average contact normal stress рavduring cold strip rolling.
