Abstract
The numerical compression instability induced by the traditional kernel functions was discussed. A new kernel function was proposed to eliminate the instability. Numerical analyses of unistrain waves with different kernel functions were performed by using corrected smoothed particle hydrodynamics (CSPH) method. The results show that the new kernel function eliminates the compression instability and ensures the numerical calculation accuracy.
