Advances on creep–fatigue damage assessment in notched components [PDF]

open access: yes, 2017
In this paper, the extended Direct Steady Cyclic Analysis method (eDSCA) within the Linear Matching Method Framework (LMMF) is combined with the Stress Modified Ductility Exhaustion method and the modified Cavity Growth Factor (CGF) for the first time ...

Damage Assessment of Nanostructures [PDF]

open access: yesKey Engineering Materials, 2007
In this paper the damage assessment of nanostructures is discussed. As an example we assess the damage of nanobeams with non destructive dynamical resonance or destructive tensile tests: a small number of nanocracks, i.e., ~10, with length of ~1nm, is accordingly estimated.

Assessing tubal damage

open access: yesJournal of Human Reproductive Sciences, 2009
The fallopian tube plays an important role in the mechanical transport and physiological sustenance of the gametes and early conceptus. Complex and coordinated neuromuscular activity, cilial action and endocrine secretions are required for successful tubal function.
