MSc
I am truly delighted to announce that finally, after 3 years of hard work and dedication, I successfully defend my MSc thesis entitled “Experimental study of the strain ratcheting in additively manufactured 316L steel”. I highly appreciate Prof. Mostafa zeinoddini and Dr. Mehdi Ezzati for their collaboration, advice and help during this long and rigid path. I…
What is Ratcheting?
A progressive accumulation of plastic strain, called strain ratcheting, occurs in ductile materials, subject to asymmetrical inelastic cyclic stressing. Ratcheting is characterised by a shift in the stress-strain hysteresis loop along the strain axis and incremental inelastic deformations. The ratcheting phenomenon is of paramount importance in the design procedure of systems, which undergo inelastic cyclic…
