✦ Synopsis

A study of direction-based models for the representation of isotropic and anisotropic hyperelastic behaviour of rubber-like materials is proposed. The interest in such models is sustained by their ability to account for the Mullins effect induced anisotropy. For such a purpose, the directional models should be initially isotropic and representative of the hyperelastic behaviour of rubber-like materials. Various models were defined according to different sets of directions. Models were tested in terms of their initial anisotropy and their ability to reproduce the classic full-network hyperelastic behaviour. Various models were proved to perform very well.

Preliminary studies aimed at developing reaction conditions for the fragment coupling between the C26-C42 fragment and the tris-oxazole fragment of ulapualide A are described. Our approach utilizes Schlosser-Wittig olefination conditions for the construction of a trans-double bond. In this study, se
