Damage in Creep Aging Process of an Al-Zn-Mg-Cu Alloy: Experiments and Modeling

open access: yesMetals, 2018
In creep age forming (CAF), large integral panel components of high-strength aluminum alloy can be shaped and strengthened under external elastic loading at an elevated temperature through creep deformation and age hardening, simultaneously. However, the

Statistical modeling of damage evolution in spallation [PDF]

open access: yes, 1988
In order to understand the mechanism of the incipient spallation in rolled metals, a one dimensional statistical mode1 on evolution of microcracks in spallation was proposed.

Applying the fractional derivative Zener model to fitting the time-dependent material viscoelasticity tested by nanoindentation

open access: yesBiosurface and Biotribology, 2018
Material viscoelasticity is of particular importance for polymers, biotissues and many others, due to the significant influence not only on the elastic response of structures, but also on their failure mechanism in actual applications. In this study, the

The Evolution of Damage Control in Concept and Practice [PDF]

open access: yesClinics in Colon and Rectal Surgery, 2017
AbstractDamage control surgery (DCS) began as an adjunct approach to hemorrhage control, seeking to facilitate the body's innate clotting ability when direct repair or ligation was impossible, but it has since become a valuable instrument for a broader collection of critically ill surgical patients in whom metabolic dysfunction is the more immediate ...
