Large amplitude oscillatory shear of pseudoplastic and elastoviscoplastic materials (2010, background): “A number of more general elastoviscoplastic models have also been proposed in the literature (see for example Mujumdar et al. (2002), Saramito (2007)); however for simplicity we focus here on the canonical elastoplastic model.”
A new elastoviscoplastic model based on the Herschel–Bulkley viscoplastic model (2009, unknown): “In [26], by introducting viscoelasticity into a viscoplastic model, a three-dimensional combination of the viscoelastic Oldroyd and viscoplastic Bingham model has been derived, and has been studied in the context of liquid foam in [5].”
On secondary loops in LAOS via self-intersection of Lissajous–Bowditch curves (2010, background): “A number of more general elastoviscoplastic models have also been proposed in the literature (see for example Mujumdar et al. (2002), Saramito (2007)); however for simplicity we focus here on the canonical elastoplastic model.”
Numerical simulations of complex yield-stress fluid flows (2017, methodology): “For the EVP stress components, Saramito (2007) has introduced plastic effects in viscoelastic models of the Oldroyd-B or the PTT type and proposed the following constitutive equation: Def ρo−1ð Þ τ∇¼epþ f τ¼ep τ ¼ep −2 1−βð ÞD¼ ¼ 0 ð36Þ where the symbol ∇ over the EVP stresses denotes the upper…”
