Rats do not consider all unfamiliar strains to be equivalent

Behavioural Processes, 2021
Humans show distinct social behaviours when we recognise social similarity in opponents that are members of the same social group. However, little attention has been paid to the role of social similarity in non-human animals. In the Wistar subject rats, the presence of an unfamiliar Wistar rat mitigated stress responses, suggesting the importance of ...

Strain linearization for structural strain evaluation and maximum equivalent structural strain criterion

International Journal of Pressure Vessels and Piping, 2016
Abstract This paper is focused on the gross plastic deformation design check of the direct route in European standard EN 13445-3 and its applications. Six methods for the evaluation of the structural strain are introduced and compared. A generally applicable method for structural strain evaluation – the strain linearization method is presented.

The equivalent strain in high pressure torsion

Materials Science and Engineering: A, 2014
Abstract The results of experiments carried out by means of high pressure torsion (HPT) are frequently described in terms of the Eichinger “equivalent” strain. When employed in conjunction with equivalent stresses derived using von Mises in conjunction with the Fields and Backofen analysis, the values of the work done/unit volume associated with the ...

Equivalent-strain method and crack vertex advance

Soviet Materials Science, 1989
An approximate approach is proposed for determining the opening of a crack and the size of the plastic zone arising ahead of the crack front for bounded bodies. The basis of the approach is the equivalent loaded-state method. The method has been tested in solving various standard problems and has been found very effective.

Strain Rates of Micropolar Continua Equivalent to Discrete Systems

Meccanica, 1997
Assemblies of rigid blocks can be perceived as fine models of rocky materials, masonry materials and any other composite material made of elements essentially undeformable with respect to the matrix. However, it is often convenient to model such materials as continua endowed with structure in the sense specified in [ ?]. In an earlier work, a continuum

Construction of the Equivalent Plastic Strain Increment

Studies in Applied Mathematics, 1972
Strain hardening plastic deformation of a material possessing a yield locus (f(σij)) which may be written as a homogeneous function of the stress components (σij), and which obeys the classical associated flow rule for metals (e.g. Bishop and Hill, 1951) is considered. The material may be anisotropic and may display plastic dilatation.

Equivalent Strains in Severe Plastic Deformation

Advanced Engineering Materials, 2003
AbstractThe concept of equivalent plastic strain is discussed. Definitions may be based on kinematic arguments (like change of geometry) or on equivalence of plastic work. Complications arise when strain is accumulated in increments with variable strain path.

Novel and Applicable Method to Determine Equivalent Strain Range and Equivalent Strain Direction Under Multiaxial Non-Proportional Loading

Volume 7A: Structures and Dynamics, 2019
Abstract When considering mechanical components that are subjected to complex loading conditions, it is difficult to achieve accurate predictions of low-cycle fatigue life. For multiaxial and non-proportional loads, the principal strain directions vary in three-dimensional space with time.
