This paper reports a finite element modeling approach to simulate the hypervelocity impact (HVI) response of composite laminate. Node–separation finite element (NSFE) method based on scalar–element–fracture technique for isotropic material in HVI simulation has been presented in the previous study. To extend NSFE to composite materials, an orthotropic node-separation finite element (ONSFE) method...
The enhanced Whipple shield is widely used on the space stations against space debris hypervelocity impact. Numerical investigation is conducted in this paper to test the concept of using the egg-box panel as the enhanced layer. Taking the flat panel as the benchmark and then the enhanced flat panel is substituted with the egg-box panel. For objective comparison all the egg-box panels have the same...
