A multiscale model for anisotropic damage and hysteresis in biodegradable polymers

چکیده
Abstract. Predicting the mechanical response of biological soft materials requires an understanding complex phenomena characterizing their microscale. In this work, we use existing versatile framework, based on assumptions statistical distribution biolpolymers at network scale, for extending our previous entropic constitutive model Worm-Like Chains networks to different deformation classes. Furthermore, include effect molecules topological constraints by introducing energy term depending second invariant Green-Cauchy tensor. way are able qualitatively reproduce, with a limited set physically meaningful parameters, range observed such as induced anisotropy, stress softening, hardening, Mullins effect, evolution permanent stretches.

passivity in waiting for godot and endgame: a psychoanalytic reading
this study intends to investigate samuel beckett’s waiting for godot and endgame under the lacanian psychoanalysis. it begins by explaining the most important concepts of lacanian psychoanalysis. the beckettian characters are studied regarding their state of unconscious, and not the state of consciousness as is common in most beckett studies. according to lacan, language plays the sole role in ...
A model for simultaneous crystallisation and biodegradation of biodegradable polymers.
This paper completes the model of biodegradation for biodegradable polymers that was previously developed by Wang et al. (Wang Y, Pan J, Han X, Sinka, Ding L. A phenomenological model for the degradation of biodegradable polymers. Biomaterials 2008;29:3393-401). Crystallisation during biodegradation was not considered in the previous work which is the topic of the current paper. For many common...
متن کاملBiodegradable Polymers
In the recent years, bio-based and biodegradable products have raised great interest since sustainable development policies tend to expand with the decreasing reserve of fossil fuel and the growing concern for the environment. These polymers bring a significant contribution to the sustainable development in view of the wider range of disposal options with minor environmental impact. As a result...
متن کاملBiodegradable Polymers
Biodegradable materials are used in packaging, agriculture, medicine and other areas. In recent years there has been an increase in interest in biodegradable polymers. Two classes of biodegradable polymers can be distinguished: synthetic or natural polymers. There are polymers produced from feedstocks derived either from petroleum resources (non renewable resources) or from biological resources...
