“…Although there are simple ways to measure such strength, theoretical prediction and modeling remain diffi cult, due to the many variables that contribute to the complicated mechanisms involved in the tearing process (Hamkins and Backer, 1980;Krook and Fox, 1945;Mukhopadhyay et al, 2006;Scelzo et al, 1994aScelzo et al, , 1994bTaylor, 1959;Teixeira et al, 1955;Teutelink et al, 2003;Frydrych, 2004, 2005;Zhong et al, 2004). Examples include the development of a del-zone in a tongue tear test (see Fig.…”

“…Therefore a dimensional analysis could combine them into fewer yet independent variables to enable development of more useful and robust models. Zhong et al (2004) employed a stochastic approach, using the Ising model combined with Monte Carlo simulation, to study the phenomenon of tongue tear failure in coated fabrics. In this approach the complicated mechanisms involved can be realistically simulated with a relatively simple algorithm.…”

“…6 Because of the multiple group variables, the mechanism of tensile failure of the envelope material is rather complex, so accurate theoretical predictions and model simulations are still quite difficult. 11,12 In the simulation research, Peirce's circular cross-sectional fiber model was considered to be original and fundamental for the mechanics research. 9 The relationships between yarn size, spacing and bending were explored in his study.…”

Owing to the increased demand of long endurance flight, lightweight, and high strength envelope becoming the main point of the stratospheric airship design, especially the research on the envelope mechanical properties a novel stratospheric airship envelope material was developed in this paper. According to the structure of the woven fabric composite, nonlinearity and orthotropy are two main characteristics of the envelope. Uniaxial tensile test was performed to study the stress-strain curves of the envelope material. It is seen that the force-displacement curve can be divided into two significant nonlinear regions and three quasi-linear regions by the analysis of the test results. To analyze the forcedisplacement curve with different regions by the statistical method, Monte Carlo simulation based on the Ising model was developed. It is found that the simulation curves coincide well with the experiment curves both in the warp and weft directions. And the results show that parameters of the envelope material including fabric strength, functional layer strength, interfacial bonding strength, and so on, are the important factors affecting the mechanical properties and they decide the force-displacement curve shape.

“…Energy based models, such as the Ising model, serve as a tool to describe stable debonding of long embedded fibres (Zhong and Pan 2003), which is comparable to the removal of hemp fibre from the core. The processes were simplified as systems consisting of the interaction of subsystems with two interchangeable states (Zhong et al 2001;Zhong and Pan 2003;Zhong et al 2004). Of particular interest is the work of Zhong and Pan (2003), which discusses the simulation of a hypothetical single-fibre-peel process of a polymer with half of its volume embedded lengthwise in a block of cured matrix.…”

2013. Application of stochastic modelling for simulating hemp fibre peeling behaviour. Canadian Biosystems Engineering/Le génie des biosystèmes au Canada 55: 2.1-2.8. The separation of fibre and core components of hemp stem is a fundamental step in hemp decortication, mechanical separation of fibre and core. This research aimed to enhance the understanding of fibre-peeling behaviour of hemp to improve the current decortication technologies. Peel tests were performed on retted and unretted hemp samples for each of two hemp varieties, USO 14 and Alyssa. Results showed that force and work required to peel did not vary with the retting condition, but with the hemp variety. The average peeling force for the Alyssa variety was 0.39 N and that for the USO 14 variety was 0.87 N. Within the Alyssa variety, the work required to peel the fibre from the core was 193 J m -2 , and the work required to peel the fibres of the USO 14 variety was 431 J m -2 . The Ising model was implemented to produce a stochastic model which simulated the peeling force obtained from the peel tests. The behaviour of the simulated peel test was similar to that observed during the peel test and the process of fibre peeling was successfully simulated through the use of a stochastic algorithm. The stochastic model simulated the average peel force to be 0.86 N for the USO 14 variety and 0.39 N for the Alyssa variety. Keywords: stochastic model, hemp, peel, debonding, fibre, core, force, work La séparation des composantes fibreuses et du coeur de la tige de chanvre est une étape fondamentale dans la décortication du chanvre par la séparation mécanique de la fibre et du coeur. Ce projet de recherche avait pour objectif d'améliorer les connaissances en ce qui à trait au comportement de séparation des fibres de chanvre pour améliorer les technologies actuelles de décortication. Des tests de séparation étaient faits sur des échantillons de chanvre roui et non roui pour chacune des deux variétés, USO 14 et Alyssa. Les résultats ont montré que la force et le travail requis pour la séparation ne variaient pas avec les conditions de rouissage mais avec la variété de chanvre. La force moyenne de séparation pour la variété Alyssa était de 0,39N et de 0,87N pour la variété USO 14. Pour la variété Alyssa, le travail requis pour séparer les fibres du coeur était de 193 J m -2 et le travail requis pour les fibres de la variété USO 14 était 431 J m -2 . Le modèle Ising était utilisé pour produire un modèle stochastique qui simulait les forces de séparation obtenues par les essais de séparation.Le comportement des tests de simulation de séparation était similaire à celui observé durant le test de séparation et le processus de séparation de la fibre était représenté efficacement avec l'utilisation de l'algorithme stochastique. Le modèle stochastique représentait la force moyenne de séparation à 0,86 N pour la variété USO 14 et à 0,39 N pour la variété Alyssa.
