Advances in Materials Science and Engineering, 2017 The viscoelastic response of commercial Al–Zn–Mg and Al–Cu–Mg alloys was measured with a dynamic-mechanical analyzer (DMA) as a function of the temperature (from 30 to 425°C) and the loading frequency (from 0.01 to 150 Hz).

Aging and rejuvenation effects on the rheological response and chemical parameters of bitumen
Journal of Materials Research and Technology, 2023 The rejuvenation efficiency of aged bitumen is the main concern when developing rejuvenating agents. It is necessary to develop a method to assess the efficiency of rejuvenators using rheological parameters in the whole frequency region. To this end, the

Effect of the contraction ratio upon viscoelastic fluid flow in three-dimensional square-square contractions [PDF]
, 2011 In this work we investigate the laminar flow through square–square sudden contractions with various contraction ratios (CR¼2.4, 4,8and12), using a Newtonian fluid and a shear-thinning viscoelastic fluid.
