Summary Terminal ballistics of concrete is of extreme importance to the military and civil communities. Over the past few decades, ultra‐high performance concrete (UHPC) has been developed for various applications in the design of protective structures because UHPC has an enhanced ballistic resistance over conventional strength concrete. Developing predictive numerical models of UHPC subjected to penetration is critical in understanding the material's enhanced performance. This study employs the advanced fundamental concrete (AFC) model, and it will run inside the reproducing kernel particle method (RKPM)‐based code known as the nonlinear meshfree analysis program (NMAP). NMAP is advantageous for modeling impact and penetration problems that exhibit extreme deformation and material fragmentation. A comprehensive experimental study was conducted to characterize the UHPC. The investigation consisted of fracture toughness testing, the utilization of nondestructive microcomputed tomography analysis, and lastly projectile penetration shots on the UHPC targets. To improve the accuracy of the model, a new scaled damage evolution law (SDEL) is employed within the microcrack informed damage model. During the homogenized macroscopic calculation, the corresponding microscopic cell needs to be dimensionally equivalent to the mesh dimension when the partial differential equation becomes ill posed and strain softening ensues. To ensure arbitrary mesh geometry for which the homogenized stress‐strain curves are derived, a size scaling law is incorporated into the homogenized tensile damage evolution law. This ensures energy‐bridging equivalence of the microscopic cell to the homogenized medium irrespective of arbitrary mesh geometry. Results of numerical investigations will be compared with results of penetration experiments.

“…The model was designed for modeling the dynamic response of concrete under high-rate loading conditions. A number of studies have shown that the AFC model can be applied to a large range of penetration type scenarios (Sherburn et al 2014;Sherburn et al 2015;Nordendale et al 2016). The AFC model used in this study follows the approach of Sherburn et al (2014) and Sherburn et al (2015), which includes the MIDM tensile damage evolution function described in Section 4.1.…”

Many continuum damage mechanics models for cementitious materials are typically phenomenological in design. Recent work has shown that a physics-based multiscale approach to modeling damage is efficient and effective. In order to use a multiscale approach, appropriate experimental data are necessary to model the microscale calculations that will then inform the continuum-scale calculations. This work uses the multiscale approach and experimentally determines the parameters necessary to model the microscale calculations. Notched three-point beam experiments were performed to determine the fracture energy of the ultra-high performance concrete known as Cor-Tuf. The fracture energy is then used by a simplified microscale calculation to determine a physics-based damage evolution equation that can be used in continuum-scale calculations. A meshfree method is used to show the usefulness of the newly determined damage evolution equation. Both a quasi-static application and a dynamic application are shown as examples.
