tensors are called scalars while rank-1 tensors are called vectors. scanned the old master copies and produced electronic versions in Portable Document Format. A tensor is de ned as a set of quantities that transform like products of the components of vectors: T0ij::: kl::: = @x0i @xm @x0j @xn @xp @x0k @xq @x0l Tmn::: pq:::: (1.1.12) These quantities are referred to as the components of the tensor. We also de ne and investigate scalar, vector and tensor elds when they are subjected to various coordinate transformations. Examples are hydrostatic pres-sure and temperature. It follows at once that scalars are tensors of rank (0,0), vectors are tensors of rank (1,0) and one-forms are tensors of rank (0,1). In addition to reviewing basic matrix and vector analysis, the concept of a tensor is cov-ered by reviewing and contrasting numerous . Volume I begins with a brief discussion of algebraic structures followed by a rather detailed discussion of the algebra of vectors and tensors. A vector is a bookkeeping tool to keep track of two pieces of information (typically magnitude and direction) for a physical quantity. Rank-2 tensors may be called dyads although this, in common use, may be restricted to the outer product of two vectors and hence is a special case of rank-2 tensors assuming it meets the requirements of a tensor and hence transforms as a tensor. A tensor is of rank (k;l) if it has kcontravariant and lcovariant indices. 1. This work represents our effort to present the basic concepts of vector and tensor analysis. Notation: We write V 1 V 2 for the vector space Y, and x 1 x 2 for (x 1;x 2). The images have not been converted to searchable text. It turns out that tensors have certain properties which are independent of the coordinate system used to describe the tensor. Examples are position, force and velocity. Closely associated with tensor calculus is the indicial or index notation. We may denote a tensor of rank (2,0) by T(P,˜ Q˜); one of rank (2,1) by T(P,˜ Q,˜ A~), etc. These topics are usually encountered in fundamental mathematics courses. proves useful for higher-order tensor analysis of anisotropic media. also called a (m,n) tensor, is defined to be a scalar function of mone-forms and nvectors that is linear in all of its arguments. different. Like rank-2 tensors, rank-3 tensors may be called triads. 1 Vectors & Tensors The mathematical modeling of the physical world requires knowledge of quite a few different mathematics subjects, such as Calculus, Differential Equations and Linear Algebra. In section 1 the indicial notation is de ned and illustrated. PREFACE FOR FIRST PRINTING This cours.e is beip.g o.fi'ered to the post"';graduate students in Su:rveying Engineering. 2!Y is a bilinear map, is called the tensor product of V 1 and V 2 if the following condition holds: (*) Whenever 1 is a basis for V 1 and 2 is a basis for V 2, then ( 1 2) := f (x 1;x 2) jx 1 2 1; x 2 2 2g is a basis for Y.
The quality of the images varies depending on the quality of the originals. 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.
