Quantifying the high-temperature separation behavior of lamellar interfaces in -TiAl under tensile loading by molecular dynamics by Ganesan, H., Scheider, I., Cyron, C.J. published at Frontiers in Materials
The python file cl_cohesive.py contains a class for calculating the traction-separation behavior of material points.
The class is named cohesive and contains a number of attributes and methods.
Some of the attributes are parameters to be given at initialization,
others are variables, which are calculated during the evolution of separation.
More information is given in the README file.
The code has been used to create the plots that contain traction-separation curves in the above publication

Remarks on Early Medieval legal charters — The legend of “dux Ingo” and his “carta sine litteris”
No full textEnea Silvio Piccolomini in his work entitled
De Europa
written in 1458, tells an interesting story defined as a legend in terms of genre about a duke called Ingo, who lived during the reign of Charlemagne. This narrative claims that in 790
dux gentis
Ingo held a feast for the inhabitants of his province where food was served to the peasants allowed to appear before him in golden and silver bowls, while to the dignitaries standing further away from him in bowls made of clay. The researchers’ attention is deservedly raised by the query how come that this parabolical story with biblical tone was included in Enea Silvio’s work; if it had been borrowed who the
auctor
might have been he borrowed it from. The answer seems to be very simple: from the
Conversio Bagoariorum et Carantanorum
drafted regarding the lawsuit proceeded against Methodius. In the case narrated in the
Conversio
Ingo sent a charter or much rather a parchment without any writing, or letters on it
(carta sine litteris)
, which provided his legate with sufficient authenticity to demand obedience from the people.In this study-after having compared the two narratives and outlined the place of De Europa in Enea Silvio Piccolomini’s oeuvre and the circumstances of the drafting and tendencies of the Conversio Bagoariorum et Carantanorum-the author attempts to answer the following questions. To what extent can duke Ingo, mentioned by Enea Silvio and not questioned in the literature for long centuries, be considered a real historical person? Does the Conversio refer to Ingo as a duke, and if it does, what is his existence as a duke and introduction in the literature as a duke owing to? What could the meaning of carta sine litteris referred to in Conversio have been, and why did Enea Silvio not take this item over although he could have put it forward as a further proof of Ingo’s dignity? To what literary prefigurations can the description of the feast held by Ingo be traced back to, and what role did it play in the Conversio? Regarding the borrowing of the Ingo story by Enea Silvio, what possible intermediary writing and author can be reckoned with
Micromechanical based derivation of traction-separation laws for cohesive model simulations
No full textAbstractA general method is proposed for the derivation of traction-separation laws for cohesive models, which is based on numerical simulations of a representative volume element with heterogeneous microstructure. The failure of this microstructure may involve various damage mechanisms, which are to be included in the simulation. From the mesoscopic response of the micromechanical model the complete traction-separation law is extracted, which in general depends on the applied triaxiality and other field quantities like loading rate. The derived traction-separation law can then be used in structural finite element analyses, where the microstructure is not modelled explicitly anymore. Instead of that, phenomenological material laws are included, namely the failure in such simulations is modelled by cohesive interface elements obeying the micromechanically derived traction-separation law identified before

Authorship as cultural performance: new perspectives in authorship studies
No full textThis article proposes a performative model of authorship, based on the historical alternation between predominantly 'weak' and 'strong' author concepts and related practices of writing, publication and reading. Based on this model, we give a brief overview of the historical development of such author concepts in English literature from the Middle Ages to the twentieth century. We argue for a more holistic approach to authorship within a cultural topography, comprising social contexts, technological and media factors, and other cultural developments, such as the distinction between privacy and the public sphere
