Characterization of crack nucleation in TA6V under fretting-fatigue loading using the potential drop technique [PDF]
, 2010 Crack initiation in a Ti-6Al-4V alloy was investigated experimentally in fretting fatigue conditions. A cylinder-plane geometry was used for the contact, and partial slip conditions were considered.

Fatigue strength tests of layered steel
Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2013 The work deals with original measurement of fatigue properties of formed layered steel material – damask steel. This is a material that exhibits a fine micro-structure as well as a regular composition of many material layers with complementary properties.
