The present work is a numerical prediction based initially on a reliable model validated by experiments under the same conditions used as ours with new concepts in Bi-composite plates. A system formulation approach of the adhesive in ductile and nonlinear damage behavior is used in this analysis This ductility is developed by the CZM technique implemented using the MATLAB program in ABAQUS computer code. For a numerical prediction of the ductile behavior of the adhesive, the CZM model is an extension of the pure modes (I and II) previously characterized in block by tests. This extension is trapezoidal in increasing stresses of the adhesive in its behavior law. The single lap joint configuration allows us to stress the glue joint to mixed-mode loading. The resistance of the assembled structures remains conditioned by the behavior of the adhesive until it is damaged and the rigidity of the attached plates. Therefore, our objective in this work is to cause the plasticization damage of the adhesive at different responses and levels. For this, the bi-composite graduation in concept and in graduation index largely plays the role of evaluation parameters. In order to test the adequacy for a good resistance, three different concepts of graduation in Bi-composite were proposed such as: concept1-concept1, concept2-concept2, and simple concept-simple concept. By these two cases of assemblies, these concepts have the advantage of having different assembly possibilities, The proposed concepts of graduated bi-composite plates showed an overcapacity of resistance on the assembly. The latter becomes important in the adequacy of concept of these assembled plates. Similarly, the results show that different responses and levels cause the damage by effect of these concepts.

Rising global energy demand has intensified the need for sustainable building practices and reduced energy consumption in the construction sector. This study investigates the energy-saving potential of integrating innovative materials into building wall structures in semiarid climates. Specifically, we examine the combination of thermal insulation made from recycled textile waste and phase change materials (PCMs) in exterior walls. Using the dynamic simulation tool TRNSYS, we analyzed heat transfer through the modified wall assembly under semiarid climate conditions typical of Marrakech, Morocco. Our results show that this "bioclimatic" design significantly impacts cooling loads more than heating demands. The modified building achieved a 52% reduction in summer energy usage compared to a conventional reference building. This energy saving translates to a 39% decrease in greenhouse gas emissions. Importantly, this study confirms that this configuration maintains thermal comfort for occupants, with particular effectiveness during the hot summer months when cooling demands are highest.

This work aims to evaluate the impact of new materials on thermal performance and energy savings. Indeed, this study shows the importance of the use of natural and recycled waste-based feather materials. For this purpose, a full-scale cell located in Casablanca was considered as a case study to build a simulation model performed on TRNSYS. This model is then used for the impact of the techniques studied on energy performance, GHG emissions, and hours of discomfort inside another cell in Casablanca. This study showed that the developed nonwovens exhibit excellent insulation performance with thermal conductivity in the range of 0.031–0.044 [W/m. K]. Moreover, the minimum energy performance is observed for developed wool insulation with a performance of 30 (KWh/year.m2). The comparison of these values with the Moroccan thermal regulation which sets a threshold of 40 (kWh/year.m2) for the annual thermal load of residential buildings in the climatic zone of Casablanca, shows that the feather waste insulation integrated into the building is mainly sufficient to meet the requirements of Moroccan regulations. Annual GHG emissions are mitigated by 44.61 for FC1, 46.54 for FC2, 47.95 for FC3, 46.59 for FW1, 46.99 for FW2 and 48.58 for FW3(%). [ABSTRACT FROM AUTHOR]
