State Equation under Proportional Nonisothermal Loading

摘要

The paper deals with the technic of construction of constuent equations under monotonous proportional loading on the basis of the model with infinite number of subelements. Processes under monotonous loading are classified. It is shown that on the basis of the studied model one can describe from a single position a wide variety of the processes of frreversible deformation. In particular the phenomenon of flow tooth is described within the frameworks of a single mechanical scheme. It is established that for all materials under extension with a constant rate of the catch translation the averaged rate of irreversible deformations of subelements decresses with deformation growth that results in the decrease of their elasticity limits. Depending on the prevailing process the materials having similar diagrams in the base experiments can display the opposite effects in the tests far from the base ones.
