The aim of this paper is to propose the simple Plane-Cap (PC) model as well as to classify an accuracy of analysis for the response of the reinforced mortar beam subjected to low velocity impact loading. The present study deals with the Smoothed Particle Hydrodynamics (SPH) method by employing Drucker-Prager (DP) with a new PC yield surface and Von-Mises (VM) yield surface for mortar material. The influence of the different material model of DP and VM that used numerically for mortar beams are studied in this paper. Besides, the new simple cap model is employed on compression, while, orthotropic constitutive equation due to the damage effect is utilized on the tension side. Finally, the results of numerical analyses are discussed by comparing them with experimental observations.
