Tensor analysis, branch of mathematics concerned with relations or laws that remain valid regardless of the system of coordinates used to specify the quantities. Such relations are called covariant. Tensors were invented as an extension of vectors to formalize the manipulation of geometric entities arising in the study of mathematical manifolds. A vector is an entity that has both magnitude.

Tensors. A tensor is a generalization of a scalar (a pure number representing the value of some physical quantity) and a vector (a geometrical arrow in space), and a tensor field is a generalization of a scalar field or vector field that assigns, respectively, a scalar or vector to each point of space.

A tensor-valued function of the position vector is called a tensor field, Tij k (x). The Gradient of a Tensor Field The gradient of a second order tensor field T is defined in a manner analogous to that of the gradient of a vector, Eqn. 1.14.2. It is the third-order tensor i j k k ij k k x T x e e e e T T grad Gradient of a Tensor Field (1.14.10).Learn More
What is tensors in TensorFlow? TensorFlow's central data type is the tensor. Tensors are the underlying components of computation and a fundamental data structure in TensorFlow. Without using complex mathematical interpretations, we can say a tensor (in TensorFlow) describes a multidimensional numerical array, with zero or n-dimensional collection of data, determined by rank, shape, and type.Learn More
Scalars, Vectors and Tensors A scalar is a physical quantity that it represented by a dimensional num-ber at a particular point in space and time. Examples are hydrostatic pres-sure and temperature. A vector is a bookkeeping tool to keep track of two pieces of information (typically magnitude and direction) for a physical quantity. Examples are position, force and velocity. The vector has.Learn More

Tensors of the same type can be added or subtracted to form new tensors. Thus, if and are tensors, then is a tensor of the same type. Note that the sum of tensors at different points in space is not a tensor if the 's are position dependent. However, under linear coordinate transformations the 's are constant, so the sum of tensors at different points behaves as a tensor under this particular.Learn More
It stands to reason, then, that a tensor field is a set of tensors associated with every point in space: for instance,. It immediately follows that a scalar field is a zeroth-order tensor field, and a vector field is a first-order tensor field. Most tensor fields encountered in physics are smoothly varying and differentiable.Learn More

The text begins with a detailed presentation of the coordinate invariant quantity, the tensor, introduced as a linear transformation. This is then followed by the formulation of the kinematics of deformation, large as well as very small, the description of stresses and the basic laws of continuum mechanics. As applications of these laws, the behaviors of certain material idealizations (models.Learn More
