In 1998 IUPAC Division IV published a document on ‘Non-Ultimate Mechanical Properties’ (Pure Appl Chem., Vol. 70, No. 3, pp. 701-754; https://dx.doi.org/10.1351/pac199870030701), in which the basic terms of mechanical properties important in polymer science were laid. Of greater importance in application, however, is the behaviour close to, or at, mechanical failure of a polymeric material. The purpose of this project is to extend the existing successful recommendations into this scientifically and technologically important field of application (i.e. the ultimate mechanical properties of polymers). The outcome of the project will be extremely beneficial also for the education of engineers in the related fields.
On the basis of the document “Definition of Terms Relating to the Non-Ultimate Properties of Polymers” published by IUPAC in 1998 [A. Kaye, R. F. T. Stepto, W. J. Work, J. V. Alemán, A. Ya. Malkin, Pure Appl. Chem. 70 (3), 701-754 (1998); https://dx.doi.org/10.1351/pac199870030701], this document supplements the definitions of terms relating to the non-ultimate mechanical properties of solid polymers and solid polymer systems by providing definitions of terms related to the ultimate mechanical behaviour of the polymeric materials, i.e., the mechanical properties just at the point where failure of those materials occurs. The document focuses in particular on the behaviour of bulk polymers, blends and composites with reference to their elastic, viscoelastic and micromechanical properties. In the final document, the terms dealing with basic definitions related to ultimate mechanical deformation phenomena (and the relevant quantities) derived experimentally will be arranged alphabetically. Various literature sources dealing with conventional mechanical characterization of polymeric materials will be the basic source of information for the final document.
As for the project on “Definition of Terms Relating to the Non-Ultimate Properties of Polymers”, published by IUPAC in 1998, the definitions will be adapted from various sources such as International Standards Organization (ISO) manuscripts on Plastics Vocabulary, ASTM publications and DIN- norms, and various encyclopaedia of materials science and engineering.
