Abstract
CFRPs (carbon fiber reinforced plastics), as a kind of fiber-reinforced plastic, present various advantages
over traditional materials regarding the specific strength, stiffness, and corrosion resistance. For this reason,
CFRPs are widely used in the space industry, like satellites and space stations, which are easily subjected to
the HVIs (hypervelocity impacts) threatened by space debris. In order to mitigate the damage of HVIs and
protect the spatial structures, it is necessary to predict the HVI process on CFRPs. Smoothed particle
hydrodynamics (SPH) method, as a mesh-free particle-based method, has been widely applied for modeling
HVI problems due to its special advantages when modeling problems with large deformations [1]. Also, SPH
is attractive for parallel computing, benefiting from its particle-based nature [2]. Considering such
advantages, we present a GPU-accelerated HVI model for composite CFRPs structures based on the SPH
method in this talk. Firstly, a metallic penetration problem is studied as a test example to validate the
numerical model. The simulation results agreed well with the published data, and nearly 350 times of speedup (GPU vs CPU) has been achieved. Then, the process of a bullet penetrating a CFRP laminate has been
investigated and the corresponding physical behaviors, such as the orthotropic property, shock response,
and delamination have been well captured as well. Finally, the HVI problem of the Whipple bumper shield,
one of the typical shields for spatial structures, has been investigated considering the secondary debris cloud
and the damage effects. Our studies have shown that the GPU-accelerated SPH model allows us to investigate
three-dimensional HVI problems with complex composite structures accurately and efficiently.
