近年来，平滑粒子流体动力学（SPH）方法的使用有所增加。然而，大多数研究限制了该方法在流体领域的应用。很少有出版物报道使用 SPH 来研究固体问题。此外，只有少量研究考虑了两种固体接触时的界面。标准SPH方法能够通过界面处粒子的相互搜索来确定两个物体的相互作用。考虑到这一点，本文提出了一种名为界面 SPH 的新策略，用于模拟弹性物体的接触。在我们的模拟中，搜索域仅包含物体的粒子，两个物体之间的相互作用是通过界面力实现的。首先，模拟两个铝矩形的碰撞，以测试模拟策略在线性界面上的有效性。随后，模拟了两个圆盘之间的碰撞，以测试弯曲界面处的策略。随后，模拟了两个弹性橡胶环的碰撞以及子弹对弹性板的撞击。最后两个模型展示了如何将本研究中使用的策略应用于弹性体大变形的模拟。最后分析了应用标准SPH方法模拟两种固体界面接触时存在的问题。模拟中采用了XSPH方法和人工应力方法，以保证模拟的稳定性。
In recent years, the use of the smoothed particle hydrodynamics (SPH) method has increased. However, most researches have restricted the application of this method to the fluids field. Few publications have reported the use of SPH to study solid problems. Moreover, only a small amount of investigations have considered the interface when two solids are in contact. The standard SPH method is able to determine the interaction of two objects through mutual search of particles at the interface. Taking this into account, herein we report a new strategy named interfacial SPH for simulating the contact of elastic objects. In our simulations, the search domain only contained the particles of the object, and the interaction between the two objects was achieved by means of the interface force. First, the collision of two aluminium rectangles was simulated in order to test the usefulness of the simulation strategy at the linear interface. Later, the collision between two discs was simulated to test the strategy at the curved interface. Subsequently, the collision of two elastic rubber rings and the impact of a bullet on an elastic plate were simulated. These last two models showed how the strategy used in the present investigation can be applied for the simulation of large deformation of elastomers. Finally, this paper analysed the problems of applying the standard SPH method in the simulation of the interface contact between two solids. The XSPH method and the artificial stress method were used in our simulations to ensure simulation stability.
