Modelling of impacted composites becomes more difficult when a ply suffers damage. It affects performance of the whole laminate generating an iterative process each time a local ply or part of its material is degraded and continues until ultimate failure. In order to model such material damages ...
7 – Impact damage modeling in laminated composite aircraft structuresLaminated composites have important and irreplaceable applications in modern aeronautical structures. They have extraordinary properties, like high strength, stiffness, and light weight. Nevertheless, a serious obstacle to more ...
A new smart polymer nanocomposite layer, based on semiconductor CuS nanoparticles embedded into an amorphous polystyrene matrix, was developed for the detection of low-velocity impact damage on composite structures. This material exhibits a combination of optical and electro-magnetic properties, in way ...

Barely visible impact damage (BVID) is developed when polymer matrix composites are subjected to impact loading. The damage has an adverse effect on structural integrity, and potentially leads to catastrophic failure.Thus it is important to employ a variety of advanced non-destructive testing (NDT)...
摘要: This paper proposes an analytical model capable of relating damage found on a composite plate to a given impactor characteristic (size and energy). The model addresses a gap in kno... 查看全部>>关键词: Structural impact Composite fuselage Damage modelling Aircraft maintenance Impact risk ...
in a damage tolerant manner.While damage is produced under very low energy,but it is bounded in a limited area and no catastrophic failure occurs under all energy levels.LVI damage area increases with the impact energy.After impact of 1.5J,nearly no visible damage is found.When the impact ...
