Kong, X Z, Fang, Q, Li, Q M, Wu, H & Crawford, J 2017, ' Modified K &C model for cratering and scabbing of concrete slab under projectile impact ', International Journal of Impact Engineering, vol. 108, pp. 217-228 . https://doi.org/10.1016/j.ijimpeng.2017.02.016
The K&C material model, which was originally developed for the structural response subjected to blast loadings, is modified to improve its numerical prediction capability for cratering and scabbing phenomena in concrete slabs subjected to projectile

A point-wise evolutionarily coupled reproducing kernel (RK)/finite element (FE) formulation was developed to model fragmentation processes induced by blast and impact loadings. In this coupled approach, each integration point defines a coupling zone
