Since natural fibers have great potential as an alternative to synthetic fibers when the components are impacted at low energies, their mechanical properties under different types of loads need to be investigated. This can be accomplished by using finite element analysis, which is based on the definition of numerical models that reproduce the objects of the physical phenomenon under study. In defining these models, many parameters of the material cards are determined by experimental tests. However, ...

In recent years, composite materials have assumed an increasingly dominant role in various industrial sectors, combining lightweight with optimal mechanical properties. In this context, natural fibers are essential for the development of eco-friendly composites, ensuring a balance between performance and sustainability via hybridization. This study provides an experimental and numerical analysis on composite laminates subjected to Low-Velocity Impact (LVI) tests at different energy levels, after ...

Nowadays, in the global composites industry, an increasing number of companies are studying high-quality innovative and green solutions, in order to achieve the environmental sustainability goals. In this context, the use of a natural fiber reinforced polymer in the design of structural components needs to be validated through experimental mechanical tests. This study provides an overview of the behaviors of flax/epoxy and hemp/epoxy laminates subjected to tensile, four-point bending, and Low-Velocity ...

In this paper the initiation and propagation of delamination in thin-walled green composite structures were studied. In particular, laminates of flax and hemp fibers with epoxy resin were investigated from experimental and numerical points of view, using the finite element code LS-DYNA. First, an experimental campaign was conducted using DCB and 4ENF tests to obtain the values of the interlaminar fracture modes, required for the cohesive fracture modeling. In addition, in-plane crashworthiness tests ...

Sialolithiasis or “salivary lithiasis” is a pathological condition that involves the formation of calcified concrements within the gland parenchyma and its ductal system of the main salivary glands of the head and neck area. Various theories of lithogenesis have been reported, but the etiology of sialoliths still remains unclear. The aim of this case report was to evaluate the biochemical composition and the surface morphology of a sialolith using energy dispersion X-ray spectroscopy (EDX) and scanning ...
