“…A detailed diagram of the hybrid algorithm is shown in Fig. 1, with its upper and lower parts presenting computation processes of SPH and FEM [29,31,58]. At the interface of the SPH and FEM domains, when a particle contacted the surface, a contact force was generated and parameters of particles and nodes were renewed.…”

“…Although SPH approaches can be applied to problems with severe distortions, they are generally not as good as the finite-element method (FEM) [23][24][25][26][27] -a mature scheme with a high efficiency, suitable for structural applications. Therefore, alongside the SPH approach, the FEM is applied here to model steel/SPS structures and analyse their damage response, considerable effort was dedicated to coupled SPH-FEM methods [28][29][30][31][32][33][34][35][36][37][38] by various researchers in the past years. Johnson et al [28,29] developed a master-slave method to describe a contact between SPH particles and finite elements and used it to simulate highvelocity impacts.…”

“…Especially the possibility to compute the deformation gradient is the large advantage of the hybrid coupling versus other strong − f orm couplings developed by Johnson [24] and Attaway et al [2]. Since the particle sums remain symmetric, it is guaranteed that the deformation gradient is computed correctly.…”

SUMMARYThis paper reviews several novel and older methods for coupling meshfree particle methods, particularly the elementfree Galerkin (EFG) method and the Smooth Particle Hydrodynamics (SPH), with finite elements. We study master slave couplings where particles are fixed across the finite element boundary, coupling via interface shape functions such that consistency conditions are satisfied, bridging domain coupling, compatibility coupling with Lagrange multipliers and hybrid coupling methods where forces from the particles are applied via their shape functions on the FE nodes and vice versa. The hybrid coupling methods are well suited for large deformations and adaptivity and the coupling procedure is independent from the particle distance and nodal arrangement. We will study the methods for several static and dynamic applications, compare the results to analytical and experimental data and show advantages and drawbacks of the methods.

“…Johnson [19] developed a coupling technique based on the master-slave contact algorithm for the interaction between finite elements and particles and simulated the penetrations of rigid projectiles into aluminum and steel plates where FEM suffered from severe element distortion. Attaway et al [20] studied the coupling of SPH with transient dynamics FE code PRONTO using a contact-like coupling algorithm. Sauer et al [21] noted the numerical instabilities in the central processing unit (CPU) intensive SPH method and applied moving least squares correction methodology to improve the consistency of the meshless SPH approximation.…”

As alternatives to the classical finite element model (FEM), a meshless smooth particle hydrodynamics (SPH) method, in which the discrete particles represent a solid domain, and a coupled FEM/SPH modeling technique were investigated for the numerical simulation of the quasi-static axial crushing of polystyrene foam-filled aluminum thin-walled aluminum tubes. The results of numerical simulations, load-deformation histories, fold lengths and specific absorbed energies, were found to show satisfactory correlations with those of experiments and FEM. The results further proved the capabilities of the SPH Method and coupled FEM/SPH modeling technique in predicting the crushing behavior of foam-filled thin-walled tubes.
