Optimal Design of Mises Truss with Respect to Time to Creep Rapture

open access: yesEngineering Transactions, 1994
The paper deals with problem of optimal choice of slope angle for bars of Mises truss in creep conditions. Results of optimization with respect to brittle creep rupture coincide with elastic solution (45°), while for ductile creep rupture there is no ...

Microstructural modelling of creep crack growth from a blunted crack [PDF]

open access: yes, 1998
The effect of crack tip blunting on the initial stages of creep crack growth is investigated by means of a planar microstructural model in which grains are represented discretely. The actual linking-up process of discrete microcracks with the macroscopic

Theoretical backgrounds of durability analysis by normalized equivalent stress functionals

open access: yes, 2003
Generalized durability diagrams and their properties are considered for a material under a multiaxial loading given by an arbitrary function of time. Material strength and durability under such loading are described in terms of durability, safety factor ...

Targeting Post‐Irradiation Thyroid Dysfunction: Electrospun Scaffolds As A Dual‐Action Approach for Antioxidant and Immune Modulation

open access: yesAdvanced Healthcare Materials, EarlyView.
Radiation‐induced hypothyroidism follows head and neck radiotherapy due to oxidative stress and inflammation. Electrospun polycaprolactone scaffolds containing adenosine have potential to modulate thyroid repair. Scaffolds enhance thyrocyte proliferation, antioxidant enzymes glutathione peroxidase and catalase, reduce senescence and apoptosis markers ...
