Subject aims expressed by acquired skills and competences

Student will be able to determine mathematically the principal quantities connected with plastic deformation and explain the rules of plastic deformation, formability and structure-forming processes in bulk forming. He will gain the skill in field of physical testing of deformation behaviour. Student will obtain the necessary theoretical basis for study of the consequent technological subject in field of material forming.

Summary

The subject forms the theoretical basis of the consequent technological subjects in field of material bulk forming. The attention is paid mainly to state of stress, deformation and deformation rate, deformation behaviour of metallic materials (including physical methods of their study) and relevant structure-forming processes.
