...Ibtissem Gahlouz; Mohamed Boutkhil Guemmour; Sadek Chellil; Ahmed Chellil; Amin Houari; Chouaib Aribi; Alper Polat; Warda Adjout; Mohamed Bey Purpose This study aims to design a damage detection and characterization system (targeting cracks and delamination) for aeronautical composite structures...

... helical orientations – on the impact behavior of laminated composite materials. By using numerical simulation, the research aims to identify lay-up configurations that can enhance energy absorption and reduce internal damage under impact loading. The ultimate goal is to propose an innovative ply design...

...Yawen Liu; Bin Sun; Tong Guo; Zhaoxia Li Purpose Damage of engineering structures is a nonlinear evolutionary process that spans across both material and structural levels, from mesoscale to macroscale. This paper aims to provide a comprehensive review of damage analysis methods at both...

.... Design/methodology/approach Fatigue monitoring requires a fatigue model of the material, the stresses at specific points of the structure, a cycle counting technique and a fatigue damage criterion. Firstly, this paper reviews existing structural health monitoring (SHM) techniques, addresses...

...Xianggang Zhang; Dapeng Deng; Jianhui Yang Purpose The purpose of this paper is to establish the horizontal displacement angle limit values under different performance level, use damage as the quantitative index of performance level and determine the design principle of the RACFST column...

...Konstantinos Stamoulis; Stelios K. Georgantzinos; G.I. Giannopoulos Purpose The present study deals with the numerical modeling of the low-velocity impact damage of laminated composites which have increasingly important applications in aerospace primary structures. Such damage, generated...

...Jafar Ali; Debasish Bandyopadhyay Purpose Condition monitoring (CM) of structures is important from safety consideration. Damage detection techniques, using inverse dynamic approaches, are important tools to improve the mathematical models for monitoring the condition of structure. Uncertainties...

... of building structures in an earthquake event. To apply the fatigue design approach using the Palmgren–Miner’s rule for steel components of the moment resisting frames requires the knowledge regarding the damage index value at fatigue failure. The purpose of this paper is to perform fatigue tests to give...

... to 400 mm diameter were used in repeated indentation tests. Force, displacement and damage growth were recorded for loading and unloading until the indenter returned to its original starting point. Findings Similar scaled trends were observed between the non-coincidental loadings. Unlike reported...

...Dr P.M.G. Moreira and Dr Paulo J. Tavares; Peter Horst Purpose – In general two main types of criteria are essential for the sizing of aircraft structural panels, namely, stability and damage tolerance. The way these criteria act and interact is very different for metallic and composite building...

.... Design/methodology/approach – The major approach of this paper was to evaluate the potential of two inspection techniques named ultrasounds, vibrations for detecting textile reinforcement defects in composites and evaluate the composite performance in the presence of a damage. Findings...

... is higher (greater than 1.39 m/s in the studied cases), the characteristic plateau usually present in compressed metal foams can vanish. For the geometries analysed, damage has a small influence on load‐deformation relations. Originality/value This paper presents and discusses differences between static...
