Tensor components of strain

It was emphasized in Section 2.2 above that the engineering components of strain were defined. The nine tensor components of strain are defined by the symmetric strain tensor 

It can be seen that this follows Ifom a general definition of the strain Eg as 

In terms of the engineering components of strain e c, ete. defined in Section 2.2

The most general linear relationship between stress and strain is obtained by assuming that each of the tensor components of stress is linearly related to all the tensor components of strain and vice versa. Thus...
