Summary |
---|
The subject is focused on theoretic introduction into consequential technological articles in field of material forming. The attention is devoted on meaning of stress, deformation and deformation rate and knowledge tensor state and deviator state of stress problems. Is mentioned demonstration differential equation of equilibrium in rectangular coordinates and primary objective theoretic stress-strain terms. |
Learning Outcomes of the Course Unit |
---|
Studednt will be able:
describe primary objective knowledge about theoretic principles of plastic deformation. Mathematical reasons of standard tension size like resistance at change volume.. Explain tension like tensor quantity with possibility subdivision after as much as tension deviator. As well analysis sizes intensity tension like resistance against deformation body and manners of graphic display. Analogy stress state on deformation and deformation velocity at forming.
