The upper-convected Maxwell (UCM) model is a generalisation of the Maxwell material for the case of large deformations using the upper-convected time derivative. The model was proposed by James G. Oldroyd. The concept is named after James Clerk Maxwell. It is the simplest observer independent constitutive equation for viscoelasticity and ...
It is named for James Clerk Maxwell who proposed the model in 1867. [2] [3] It is also known as a Maxwell fluid. A generalization of the scalar relation to a tensor equation lacks motivation from more microscopic models and does not comply with the concept of material objectivity. However, these criteria are fulfilled by the Upper-convected ...
The Oldroyd-B model is an extension of the Upper Convected Maxwell model and is interpreted as a solvent filled with elastic bead and spring dumbbells. The model is named after its creator James G. Oldroyd. [13] [14] [15]
The Oldroyd-B model is a constitutive model used to describe the flow of viscoelastic fluids. This model can be regarded as an extension of the upper-convected Maxwell model and is equivalent to a fluid filled with elastic bead and spring dumbbells. The model is named after its creator James G. Oldroyd. [1]
In continuum mechanics, including fluid dynamics, an upper-convected time derivative or Oldroyd derivative, named after James G. Oldroyd, is the rate of change of some tensor property of a small parcel of fluid that is written in the coordinate system rotating and stretching with the fluid. The operator is specified by the following formula:
Robert Capone, 51, of Philadelphia; LeeAnn Branco, 43, of Bristol, R.I. and Joseph Parenti, 39, Cranston, R.I., were charged with multiple counts of forgery and theft related to selling the items ...
The problem, according to co-owner Paul Allen, was Traf-O-Data’s business model and the fact that neither Gates, Allen nor Gilbert did any research on how to grow such a business.
Near-Earth asteroid Bennu has a slim chance of colliding with Earth in 2182. If it does, the impact could trigger a global winter that affects our planet for years.
