Literaturas magrebinas de expressão francesa: o desafio identitário de traduzir o(s) outro(s)

A interrogação sobre o estatuto da língua na qual se escreve é um imperativo para os escritores dos chamados “espaços excêntricos” divididos entre a herança da língua do colonizador e a diversidade dos múltiplos idiomas locais. Escrever nesse contexto é travar um enfrentamento direto com questão da língua, visto que o escritor estabelece com a “língua literária”, que nem sempre é sua língua materna nem sua língua nacional, relações extremamente complexas. No caso específico dos escritores magrebinos de língua francesa, podemos afirmar que suas escritas literárias funcionam como uma espécie de tradução do mundo árabe no Ocidente, como uma mise-en-scène escritural na tentativa de resgatar o passado colonial, as dilacerações subjetivas e as rupturas identitárias. Desta forma, a partir da análise da obra La mémoire tatouée: autobiographie d’un décolonisé (1971), do escritor marroquino AbdelKebir Khatibi, procuraremos mostrar como as questões políticas e identitárias inscrevem-se na tessitura do literário com o intuito de traduzir o outro numa dimensão que ultrapassa os efeitos de ordem linguística para se configurarem como um ato de tradução entre as culturas, os povos e, como diria Khatibi, entre as espiritualidades.

Application of the embedded element technique to predict interlaminar failure

In this study a modelling technique, namely, the embedded element method is assessed to evaluate its ability to predict Mode I interlaminar failure. The embedded element technique takes advantage of the embedded constraint in ABAQUS and allows the two constituents, fibre and matrix, to be meshed independently. Since the two constituents can be meshed independently a contiguous mesh is not required and the time taken to create an acceptable mesh is significantly reduced. The embedded element technique has been used to model fibre-reinforced composite structures, however, to date no studies have been conducted which combine the embedded element technique with an interlaminar damage model. The work described herein evaluates the ability of the embedded element technique to predict mode I interlaminar failure. DCB specimens were modelled using the embedded element method and a traditional 3D solid FE modelling approach with the predictions compared against experimental data. Both modelling approaches provided good agreement with experimental results. The good agreement demonstrates that the embedded element technique is capable of providing a response that is equivalent to a traditional 3D solid FE models and is particularly suited to modelling thick composite structures with complex geometry.

A hybrid embedded cohesive element method for predicting matrix cracking in composites

The complex architecture of many fibre-reinforced composites makes the generation of finite element meshes a labour-intensive process. The embedded element method, which allows the matrix and fibre reinforcement to be meshed separately, offers a computationally efficient approach to reduce the time and cost of meshing. In this paper we present a new approach of introducing cohesive elements into the matrix domain to enable the prediction of matrix cracking using the embedded element method. To validate this approach, experiments were carried out using a modified Double Cantilever Beam with ply drops, with the results being compared with model predictions. Crack deflection was observed at the ply drop region, due to the differences in stiffness, strength and toughness at the bi-material interface. The new modelling technique yields accurate predictions of the failure process in composites, including fracture loads and crack deflection path.

Simulation of progressive damage in composites using the enhanced embedded element technique

Analysis of complex composite structures requires a fine contiguous mesh of threedimensional (3D) solid elements. The embedded element technique is a promising technique for predicting stiffness and stress. This paper presents a new method for enhancing the embedded element with continuum damage mechanics methods for predicting the evolution of damage in fiber reinforced composite structures. Comparison of the model prediction with experimental results reveals an excellent correlation between the tensile strength of quasi-isotropic laminate with an open hole. The embedded element technique allows the fiber reinforcement and matrix domains to be meshed independently and failure is evaluated separately in each domain. The enhanced embedded element approach allows the failure modes to be observed, specifically, the evolution of matrix cracking and fiber rupture. Compared to the traditional contiguous mesh finite element method, the present modelling technique demonstrates a clear advantage in predicting the experimentally observed failure modes and accurate characterisation of intralaminar fracture.
