The focus of this paper is the presentation of linear and angular components of logarithmic strain tensor determination that are useful in the description of large plastic deformation. The definition of logarithmic strain is obtained from law of energy transformation and conservation. The linear and angular components of logarithmic strain tensor are compared with the conventional strain. The differences between the conventional and logarithmic (true or natural strain) are presented in some obtained diagrams. The components of logarithmic strain are useful in the experimental analysis of strain field in the cold forming processes, in the mechanical characteristics of the materials determination, and other application in the mechanics of continuum media.
