title = "Normal Impact of Rod on Half Space",
abstract = "Rod-wall model is common in engineering cases, and the wall is reduced to a half space in this study. The compliance of the two objects in normal elastic collision is considered by coupling continuum mechanics and Hertz contact model. The contact model is studied using numerical simulation, and quasi-static contact model cannot be directly applied in impact. A partial derivative equation group is established, and the analytical solution is obtained by using modal superposition. After contact algorithm selection and mesh convergence analysis in numerical simulation, the computed results are compared with the analytical counterparts for three half-space materials and the results from literature. The theoretical model makes excellent predictions. Softer half space leads to longer rising edge of loading and longer contact duration, but the contact-impact force does not necessarily reach a plateau value.",
