2.2.4 Strain–displacement relations: the strain tensor The strain tensor is defined as (2.12)εij=12(ui,j+uj,i)i,j=1,2,3 where the differentiation shorthand Eq. (2.5) was used. In longhand, Eq. (2.12) is written as (2.13)εij=12(∂ui∂xj+∂uj∂xi)i,j=1,2,3 It is...
This chapter discusses the derivation of such a quantity, the strain tensor. It presents a detailed derivation of a number of properties of the strain tensor not only because of the importance of these properties, but also because it turns out that many of the properties can be transferred ...

In the undeformed body we establish a coordinate system x i and permanently affix the values of its coordinates to each material point (particle). This means that such points will also be known by the same values x i even after deformation, although moved to a different place. In other ...
