From the Palace of Ryswick to the Sultan’s Seraglio: The Ottoman Translation and Interpretation of a Christian European Peace Treaty

The inclusion of peace treaty articles between Christian powers in an Ottoman historical work of the late seventeenth century is unquestionably distinctive. The article presents an Ottoman translation of the Treaty of Ryswick (1697) concluded between the French king and the German emperor. This translation is included by the late seventeenth – early eighteenth-century Ottoman historian and palace official Silāḥdār Fındıklılı Meḥmed Aġa in his historical work called ‘The Book of Victory’ (Nuṣretnāme). With this unique text as its basis, the article will first attempt to place the translation in its historical context and explain the possible reasons for its inclusion by Silahdar in his history. Secondly, to morphologically evaluate the text to bring to the fore the translation strategies adopted and to explore the reception and the degree of understanding by the Ottoman side of the basic terms and linguistic topoi of a Christian European peace treaty. And lastly, to analyse the specific interpretation ascribed to the Ryswick agreement by the Ottoman leadership

An unconstrained integral approximation of large sliding frictional contact between deformable solids

International audienceThis paper presents a new integral approximation of frictional contact problems under finite deformations and large sliding. Similar to other augmented Lagrangian based formulations, the proposed method expresses impenetrability, friction and the relevant complementarity conditions as a non-smooth equation, consistently linearized and incorporated in a generalized Newton solution process. However, instead of enforcing the non-smooth complementarity equation in the already discretized system, a corresponding weak formulation in the continuous setting is considered and discretized through a standard Galerkin procedure. Such an integral handling of the contact and friction complementarity conditions, applied previously only to frictional contact problems under small deformations, is extended in the present paper to contact with Coulomb friction between solids undergoing large deformations. In total, the proposed method is relatively simple to implement, while its robustness is illustrated through numerical examples in two and three dimensions

Internal contact modeling for finite strain topology optimization

The present work proposes an extension of the third medium contact method for solving structural topology optimization problems that involve and exploit self-contact. A new regularization of the void region, which acts as the contact medium, makes the method suitable for cases with very large deformations. The proposed contact method is implemented in a second order topology optimization framework, which employs a coupled simultaneous solution of the mechanical, design update, and adjoint problems. All three problems are derived and presented in weak form, and discretized with finite elements of suitable order. The capabilities and accuracy of the developed method are demonstrated in a topology optimization problem for achieving a desired non-linear force-displacement path
