Description: Technical report
Abstract: A new constitutive model, the Advanced Fundamental Concrete (AFC) model, was developed for simulating the penetration of projectiles into concrete. Although relatively simple, the model is very robust and fast-running and contains a three-invariant failure surface and nonlinear loading and unloading in hydrostatic compression. This new capability is an adjunct to the Virtual Penetration Laboratory (VPL) software package to address the challenges of determining penetration resistance (PR) equations for high-strength concretes. The Continuous Evolutionary Algorithms automatic fitting routine was used to fit the new model to laboratory mechanical properties for two high-strength concretes. These model fits were implemented into a finite-element code and used in numerical simulations of projectile perforation and penetration experiments. Initial comparisons between results of the simulations and the experiments indicate that the AFC model shows significant promise for use in numerical simulations involving concrete and high-strength geologic materials. Finally, the AFC model in conjunction with the VPL software package was used to develop a PR equation for a high-strength concrete.
