Evaluation of the Mechanical Behavior of a Biocomposite Material in a Fuselage Section Numerical Drop Test

Abstract

The ever-increasing need for eco-compatibility in all sectors of industry is pushing scientific research to look for the so-called environmentally friendly materials characterized by minimal environmental impact during the manufacturing process and high recyclability. In the aeronautical sector composites are well established for primary and secondary structures, but alternative biocompatible solutions are found out even if great efforts are being required to improve their properties. In this work, the mechanical behavior of a biocomposite material is tested by implementing it in an existing numerical model of a fuselage section subject to a vertical drop test. Deformations and failures of biocomposite parts are evaluated providing indications on their possible compliance with crashworthiness and airworthiness requirements.

Development of Numerical Simulation Techniques for the Analysis of a Rollover Tractor

“…Numerical modeling is finding increasing applications in certification procedures, and the continuous progress of the commercial finite element (FE) codes is making the design practice faster and less expensive than the experiments. [ 6–10 ]…”

“…Numerical modeling is finding increasing applications in certification procedures, and the continuous progress of the commercial finite element (FE) codes is making the design practice faster and less expensive than the experiments. [6][7][8][9][10] Among the various methodologies used for numerical simulation applied to passive safety, two approaches were used in this work: Hybrid: FE method (FEM) and multibody in series and Full FEM (LS-Dyna is a trademark of the company Livermore Software Technology Corporation).…”

FE Model for Bird Strike Simulation on ARALL Leading Edge

“…Since their high costs in aerospace, the certification tests can be supported by numerical analyses, using, for example, the finite element method (FEM). [5][6][7][8][9][10][11][12][13] This method reduces the number of destructive physical tests required and makes the certification verification faster. In this paper, a FE model DOI: 10.1002/masy.202100475 for the simulation of a bird strike event on a leading edge has been carried out.…”
