TL;DR: In this article, a modified SPH approach is presented to deal with the unbalanced interactions between the particles with different support domains, where a Lagrangian kernel is introduced to eliminate spurious distortions of the domain of material stability and the gradient is corrected by a linear transformation so that linear completeness is satisfied.
