Computational Modeling, Simulation, and Tailoring of Nonpenetrating Impact on a Generic Structure
Publication: Journal of Aerospace Engineering
Volume 29, Issue 3
Abstract
A computational modeling and simulation study is carried out to gain insight and formulate strategy for the design and tailoring of panel-like space structure that can withstand space debris impact without penetration. To represent a generic engineering structure, the impacted panel structure is modeled as a set of bonded plates. The analysis is based on fundamental principles, which are elaborated and numerically simulated. The objective is to identify optimum configuration in terms of loading, structural dimensions, material properties, and composite layup. The analyses are based on dynamic response with emphasis on the elastic region. The direct numerical simulation is carried out in parallel for the analysis, synthesis, parametric study, and optimization. Simulation results of impact loading by a spherical rigid body at certain velocity perpendicular to the panel show how fiber-metal laminates can be structurally tailored to achieve a nonpenetrating impact.
