existence and approximate $l^{p}$ and continuous solution of nonlinear integral equations of the hammerstein and volterra types
بسیاری از پدیده ها در جهان ما اساساً غیرخطی هستند، و توسط معادلات غیرخطی بیان شده اند. از آنجا که ظهور کامپیوترهای رقمی با عملکرد بالا، حل مسایل خطی را آسان تر می کند. با این حال، به طور کلی به دست آوردن جوابهای دقیق از مسایل غیرخطی دشوار است. روش عددی، به طور کلی محاسبه پیچیده مسایل غیرخطی را اداره می کند. با این حال، دادن نقاط به یک منحنی و به دست آوردن منحنی کامل که اغلب پرهزینه و ...
15 صفحه اولLinear Viscoelasticity of Concentrated Emulsions
The linear viscoelastic response of an ordered dense emulsion is explored by numerical simulation. At concentrations below maximum packing, the stress relaxation is dominated by a single time scale associated with lubrication, which diverges at maximum packing. For concentrations above maximum packing, the stress relaxation is dominated by fast time scales of the order of the drop relaxation ti...
متن کاملRotational relaxation time of rigid rod-like macromolecule in concentrated solution
2014 A theory is developed on the rotational relaxation time 03C4r of rigid rod-like molecules in concentrated solutions. The result is 03C4r oc c2 L9(03B1 cL2 d)-2 (In (L/d))-1 , where c is the concentration of rods, L and d are the rod length and diameter respectively and 03B1 is a certain numerical factor. This relaxation time is related to the static viscosity and is found to be in good agr...
متن کاملNonlinear magneto-viscoelasticity of transversally isotropic magneto-active polymers.
Iron-filled magnetorheological polymers, when cured in the presence of a magnetic field, result in having a transversely isotropic structure with iron particles forming chains along the direction of applied magnetic induction. In this work, we model the magneto-viscoelastic deformation (and magnetization) process of such polymers. Components of the deformation gradient and the applied magnetic ...
متن کاملModels for spatial polymerization dynamics of rod-like polymers.
We investigate the polymerization kinetics of rod-like polymer filaments interacting with a distribution of monomer in one spatial dimension (e.g. along a narrow tube). We consider a variety of possible cases, including competition by the filament tips for the available monomer, and behaviour analogous to "treadmilling" in which the polymer adds subunits to one end and loses them at the other e...
