A benchmark test sede on concrete perforation was conducted with an instrumented spinning projectile with 152 mm diameter. Three tests were conducted with unreinforced concrete, with the approximate cube strength of 100 MPa. The concrete was tested with standard methods to obtain E-modulus, cube strength and splitting strength. The behavior of the concrete during tri-axial loading was tested with passive confinement of the concrete by a GREAC cell. The tests were compared with numerical simulations with Autodyn 2D using the RHT concrete model. This material model is described in the report, and its behaviour tested against simple loading cases, i.e. uni-axial strain and stress. However, there are parameters for the model that are difficult to obtain and thereby makes the use of the material model difficult. Both Euler and Lagrange formulations were used for comparison of the simulation of concrete perforation. The advantage with the Eulerian formulation is that it uses a fixed element mesh, and because of this avoids the problems associated with the distorted elements and numerical erosion used for a Lagrange formulation. A simple pressure dependent yield model was used for a few simulations vvith the Eulerian element formulation for comparison with the RHT concrete model.
