Wytrzymałość stalowych prętów z karbem przy rozciąganiu w podwyższonych temperaturach

Karol Turski
The paper deals with the influence of temperature between 20 to 700 deg C on the behaviour of axially-symmetric rods subject to tension. To compare the yield conditions of rods stretched at different temperatures, a new definition of the yield point is introduced. It is assumed that yielding develops when the work dissipated equals a definite fraction of the total plastic work measured up to moment of the force reaching its maximum.
