“…, K 1 , G, n, S, t 0 , t m JC material model constants (see Table 2) and plug inner parts is 0.125 mm, which is the same as value used by Quan et al [7] who conducted numerical simulations (without pre-stress) for the same experiments. The Lagrangian element sizes in the SiC target and outer parts of the plugs are 0.15 mm and 0.125 mm, respectively.…”

“…Those studies showed that the model accurately predicts the mechanical responses of a number of ceramic materials. Reference (18), for an example, utilized the model to study impact of a long rod against a silicon carbide, and showed that the prediction is in a good agreement with the experimental data. In addition, References (17) and (19) showed that the JH material model satisfactorily estimated the elastic responses of the boron-carbide and silicon-carbide plates.…”

“…And finally, Reference (5) demonstrated that the model successfully simulated fragmentation of an alumina ceramic sandwiched with a rubber and a glass/epoxy composite. Because the material model has been widely adopted, currently the model can be found in many finite element and finite volumes codes such as AUTODYN (18) , LS-DYNA (2) , CTH and EPIC.…”

This paper presents characterization and evaluation of a silicon nitride plate subjected to repeated impact by a small but hard particle at velocity in a range from 80 to 160 m/s. It specifically focuses on damage patterns in relation to repeated impacts. In addition, the paper also provides a finite element analysis in conjunction with the Tuler-Butcher damage model that is employed to study the formation of the damages during the multiple impact events. The results of the analysis using a very fine mesh indicated that during the contact of the projectile and the plate, the area beneath the contact surface is mainly governed by a compressive stress state. However, a small-adjacent area encircled the compressed region was in a high tensile stress state. The largest tensile stress in the area instantly occurred after the projectile touched the ceramic within a time significantly shorter than the time required for the maximum contact. Majority of the ring cracks observed in the experiments occurred in this area. Furthermore, the ring cracks grew upon further application of impact. Finally, the analysis indicated that the growth of the ring crack led to formation of the spall or the cone crack.

Abstract. In this work the Godunov Smoothed Particle Hydrodynamics (SPH) method for material with strength is extended to second order in space. This is achieved by separating the continuum equations of motion into their constituent hydrodynamic and deviatoric parts and using a MUSCL-type reconstruction and limiting procedure for the left and right Riemann states. The split equations are then advanced in time sequentially using a first-order operator splitting procedure. The resulting equations require no user defined artificial damping parameters as sufficient numerical dissipation is introduced through the use of a Riemann solver. One and two dimensional elastic-plastic flows are chosen to demonstrate the efficacy of the proposed formulation and the results are compared with exact solutions, the original first order scheme and the standard artificial viscosity SPH scheme. The new method is then applied to the simulation of a representative ballistic impact on a ceramic armour material.
