...Sofiane Talbi; Mokadem Salem; Belaïd Mechab; Tewfik Ghomari; Ahmed Allem; Belabbes Bachir Bouiadjra; Benelmaarouf Mehdi Purpose This study provides an analysis of patch repair for cracked aircraft structures. Delamination is a type of damage that affects the patch's behavior. The purpose...

... used for the monitoring of relevant delamination increments. The FE model of the panel was created in Abaqus to study panel dynamic characteristics. Findings No delamination progress was observed by NDT testing even if dynamic characteristics, especially modal frequency, of the panel changed during...

...Sunil Bhat; S. Narayanan Purpose – Since failure of laminated composites by delaminations is common, the purpose of this paper is to present a numerical procedure to check the stability of delaminations in fiber metal laminate (Glare), with different possible damage configurations, under uni...

... simulation. However, differently from VCCT, three-dimensional fatigue de-bonding/delamination with CZM is not yet state-of-art in FE softwares. where N_f represents the number of cycles to damage initiation in the cohesive element, β and α two parameters...

...Namita Nanda; S.K. Sahu; J.N. Bandyopadhyay Purpose – The purpose of this paper is to study the nonlinear forced vibration responses of delaminated composite shells in hygrothermal environments. Design/methodology/approach – Finite element method using an eight-noded C0 continuity...

...Jayaram Mohanty; Shishir Kr. Sahu; Pravat Kr. Parhi Purpose With the widespread use of the composites over other metallic materials in different fields of engineering, studies on damages of composite structures have assumed great importance. Among various kinds of damages, delamination is of very...
