Název v původním jazyce

Cyclic plasticity of additively manufactured metals

Popis výsledku v původním jazyce

This book chapter first explains some fundamentals of additive manufacturing of metals. The scanning strategies and printing parameters in the frame of Selective Laser Melting technology are discussed with a special attention paid to the influence of printing parameters on mechanical properties, density of printed material and surface roughness. Then, studies on anisotropy of metallic alloys prepared by additive manufacturing, namely Ti-6Al-4V and a maraging steel, are discussed, showing the importance of consideration of anisotropic yield criterion consideration in cyclic plasticity models. The anisotropy of Ti-6Al-4V is presented also for cyclic plasticity investigated under uniaxial loading. A comparison of stress-strain behaviour of stainless steel 316L follows. High yield strength of additive manufactured SS316L gained without any heat treatment lead to the good ratcheting as well as low-cycle fatigue performance. Finally, benefits of a new accelerated technique based on digital image correlation measurements considering standard fatigue test specimens are presented. Numerical modelling by a cyclic plasticity model with memory surface shows, that the influence of mean stress and stress amplitude on uniaxial ratcheting behaviour of additive manufactured SS316L is well described by the Abdel-Karim - Ohno kinematic hardening rule.
