Continuum mechanics deals with the mechanical behavior of materials – modeled as a continuous mass, rather than as a set of discrete particles. One of the centers of research in continuum mechanics is at the University of Birmingham.

read moreRicci calculus describes the rules of index notation and manipulation for tensors and tensor fields on a differentiable manifold. It is another name for absolute differential calculus, which is the foundation of tensor calculus. The Ricci Curvature Tensor is a fundamental component…
read moreEinstein Summation Notation is a notational convention that implies summation over a set of indexed terms in a formula. It is simply meant as a shortcut in the writing of formulas. It is primarily used in the application of linear algebra to…
read moreThe stress–energy tensor is a tensor physical quantity. A vector quantity is a tensor quantity that contains two components. A scalar quantity is a tensor quantity that contains only one component. These are special cases of tensors, being the simplest kind. But…
read moreA perfect fluid can be completely characterized by its rest frame mass density and isotropic pressure . Specifically, perfect fluids have no shear stresses, viscosity, or heat conduction. Real fluids are “sticky” and contain (and conduct) heat. Perfect fluids are idealized models…
read moreAdiabatic means heat does not enter or leave the system concerned.
read moreThe Metric Tensor in General Relativity is a Set of 10 parameters ascribed to each point in space, the values of which describe the geometry of spacetime. Metric means “measure,” and a tensor is simply the higher dimensional analogue of vector, i.e….
