Smoothed particle hydrodynamics (SPH), as one of the earliest meshfree methods, has broad prospects in modeling a wide range of problems in engineering and science, including extremely large deformation problems such as explosion and high velocity impact. This paper aims to provide a comprehensive overview on the recent advances of SPH method in the fields of fluid, solid, and biomechanics. First, the theory of SPH is described, and improved algorithms of SPH with high accuracy are summarized, such as the finite particle method (FPM). Techniques used in SPH method for simulating fluid, solid and biomechanics problems are discussed. The δ -SPH method and Godunov SPH (GSPH) based on the Riemann model are described for handling instability issues in fluid dynamics. Next, the interface contact algorithm for fluid-structure interaction is also discussed. The common algorithms for improving the tensile instability and the framework of total Lagrangian SPH are examined for challenging tasks in solid mechanics. In terms of biomechanics, the governing equations and the coupling forces based on SPH method are exemplified. Then, various typical engineering applications and recent advances are elaborated. The application of fluid mainly depicts the interaction between fluid and rigid body as well as elastomer, while some complicated fluid-structure interaction ocean engineering problems are also presented. In the aspect of solid dynamics, galaxy, geotechnical mechanics, explosion and impact, and additive manufacturing are summarized. Furthermore, the recent advancements of SPH method in biomechanics, such as hemodynamically and gut health, are discussed in general. In addition, to overcome the limitations of computational efficiency and computational scale, the multiscale adaptive resolution, the parallel algorithm and the automated mesh generation are addressed. The development of SPH software in China and abroad is also summarized. Finally, the challenging task of SPH method in the future is summarized. In future research work, the establishment of multi-scale coupled SPH model and deep learning technology in solid and biodynamics will be the focus of expanding the engineering applications of SPH methods.

Polymeric composites are exposed to erosion by solid particles in many different applications in various industries. The objective of this dissertation is to understand and model the material removal mechanisms occurring when particle-reinforced epoxy composites are subject to solid particle erosion. Experiments on alumina particulate-reinforced epoxy composites using angular silicon carbide abrasive particles revealed that the dominant erosion mechanisms depended, to a large extent, on the magnitude of three dimensionless parameters. These parameters depended on process variables such as abrasive particle size, kinetic energy, reinforcement size, content and material properties. It was also observed that the use of coupling agent was effective in strengthening the composites interfacial strength leading to improving their erosion resistance. It was found that with alumina reinforcements, reinforcement erosion and fracture resulted in little to no improvement in erosion resistance compared to the neat epoxy. However, when soft rubber or zirconia reinforcements were used, significant gains in erosion resistance were observed. For the rubber reinforcements, a novel rule of mixtures based on the erosion rates and areal coverages of the two phases is proposed. Using a model that was developed to predict the areal coverages given the reinforcement size and volume fraction, the mixture rule was shown to accurately predict the measured erosion rates. To better understand the erosion mechanisms of the zirconia-reinforced system, numerical models of the erosion of the neat epoxy and composite were developed. Using smoothed particle hydrodynamics (SPH) coupled with finite elements (FE), the developed model correctly predicted the measured neat epoxy steady-state erosion rate, incubation period length, and dominant erosion mechanisms. The SPH/FE model of the zirconia-reinforced composites assumed that, because of their relatively high fracture toughness, the reinforcements did not fracture. The model accurately predicted the significant improvement of the erosion resistance and the erosion mechanisms associated with using these tougher ceramic particles, at both oblique and perpendicular incidences. The methodologies presented in this thesis aid in determining the process and material parameters that most affect the erosion of particulate composites and, therefore, can be used in the material design process to improve erosion resistance. Although only particle-reinforced epoxy matrix-systems were studied, it is likely that many of the same phenomena will be present in other particulate polymer-matrix composites.
