...Yingying Hu; Francesco Romanò; James B. Grotberg We study the effects of surface tension and yield stress on mucus plug rupture. A three-dimensional simplified configuration is employed to simulate mucus plug rupture in a collapsed lung airway of the tenth generation. The Herschel–Bulkley model...

... was obtained through a suitable linear transformation of the stress tensor components to define the properties of the real anisotropic material in terms of a fictitious isotropic solid. A tension-compression yield stress mismatch and a direction-dependent yield stress are allowed for. The constitutive...

... the shear-thinning and yield stress properties of blood. The presence of hemoglobin is also considered. Far from the cylinder, a pulsatile blood flow in the x direction is prescribed, represented by a time periodic (sinusoidal) component superimposed on a steady velocity. The dimensionless parameters...

...Hideyuki Kimpara; Masami Iwamoto; Isao Watanabe; Kazuo Miki; Jong B. Lee; King H. Yang; Albert I. King The mass density, Young’s modulus ( E ) , tangent modulus ( E t ) , and yield stress ( σ y ) of the human ribs, sternum, internal organs, and muscles play important roles when determining impact...

The choice...

... the interspecimen heterogeneity in yield stresses and strains. Two specimens were further analyzed to determine the yield properties for a wide range of biaxial strain loading conditions. The locations and quantities of tissue level yielding were compared for on-axis, transverse, and biaxial apparent level yielding...
