Publikováno v: Metals, Vol 11, Iss 3, p 475 (2021)

In this work two approaches to the description of short fatigue crack growth rate under large-scale yielding condition were comprehensively tested: (i) plastic component of the J-integral and (ii) Polák model of crack propagation. The ability to pre

Publikováno v: Procedia Structural Integrity. 23:269-274

Austenitic stainless steel 316L was tested at room temperature in three different cycling modes – axial tension/compression, pure torsional and multiaxial in phase mode with the same equivalent strain amplitude. Two types of hollow cylindrical spec
