“…The disadvantages of the above-mentioned methods may be compensated for by the use of mesh-free methods, e.g., the particle-based SPH method [ 31 ]. Each of the above-mentioned methods can be used alternately in order to obtain the results closest to the experimental findings.…”

This article presents an analysis of the effectiveness of available numerical techniques in mapping the characteristic behavior of ballistic ceramics under projectile impact conditions. As part of the work, the ballistic tests were performed on the layered ceramic/steel composite armor and tested with the 7.62 × 39 mm, armor-piercing incendiary (API) BZ projectile. The experimental tests were then mapped using computer simulations. In numerical analyses, four different techniques were used to describe cubic ceramic tiles Al2O3 placed on the ARMOX 500T steel backing plate, i.e.,: the Finite Element Method without Erosion (FEM), Finite Element with erosion (FEM + Erosion), Smoothed Particles Hydrodynamics (SPH) and a hybrid method that converts finite elements to SPH particles after exceeding the defined failure criteria (FEM to SPH conversion). The effectiveness of the individual methods was compared in terms of quality (mapping of characteristic phenomena occurring during the penetration process), quantity (bulge height of the backing plate) and time needed to complete the calculations. On the basis of the results of the experiments and numerical simulations, it was noticed that the most accurate reproduction of the phenomenon of ballistic impact of AP projectiles on ceramic/steel composite armor can be obtained by using a hybrid method, incorporating the conversion of finite elements into SPH particles. This method should be used in cases where accuracy of the results is more important than the time required to complete the calculations. In other situations where the purpose of the calculation is not to determine, for example, the exact value of penetration depth but only to observe a certain trend, the FEM method with defined erosion criteria (variant 2), which is more than 10 times faster, can be successfully used.

“…In contrast, as one of the mesh‐free methods, the particle method, represented by the smoothed particle hydrodynamics (SPH) method, 56 has been developed to solve crack‐related problems, including brittle fracture and dynamic fracture 57–62 . It is thought that the particle method has good potential to solve them.…”

The present study discusses fatigue crack propagation simulation using smoothed particle hydrodynamics for nonplanar crack propagation problems in a three‐dimensional body. The algorithm for the nonplanar crack to propagate in the solid and C0 continuous crack front model, called the “chained crack front line” for the nonplanar crack, is proposed. The model is used to simulate some of the conducted experimental fatigue tests of nonplanar crack propagation. The model results matched experimental results. We conclude that the proposed method is a valuable tool in estimating the nonplanar fatigue crack propagation phenomena in actual mechanical structures.
