Local damage to reinforced concrete structures caused by impact of aircraft engine missiles Part 1. Test program, method and results

Local Effects of Impact into Concrete Structure

“…Limits of applicability of these formulae highly depend on the original experiment. Medium and larger scale tests were done by Rüdiger and Riech [8], Kojima [9] and Sugano [10,11].…”

“…One of the best documented multi-scale test series was executed by Sugano and his team [10,11]. They used flat-nose, cylindrical, hard and semi-hard models of a GE J-79 military jet engine in three different scales (1 / 7.5, 1 / 2.5, 1 / 1) and concrete target plates with different size, thickness and reinforcement.…”

“…Reinforcement is not modeled at this stage, because according to test results [10,11], it hardly affects the perforation and penetration properties (in case of high velocity impacts and normal amount of reinforcement). Material model is CONC-35MPa explicit material model of Ansys Workbench Explicit that includes the RHT strength model [14] that describes rate-dependent elastic limit, failure and residual surfaces, and also includes state equations for pressure dependence of compression and density.…”

Failure analysis of UHPFRC panels subjected to aircraft engine model impact

“…Reidel et al [10] carried out an experimental series of scaled aircraft engine impact tests with UHPFRC panels. In Riedel's works, the investigations focused on A C C E P T E D M A N U S C R I P T ACCEPTED MANUSCRIPT 3 the material behavior and the damage intensity in comparison to conventional concrete carried out by Sugano et al [11]. However, the material properties used by Reidel and Sugano were not identical, which may lead to a non-homologous comparison.…”

Detailed analytical methods for simulation of concrete target resistance against F-4D jet impact

“…It was speculated that most of the energy was used to move the target rather than causing signi icant damage on the target. Considering these perspectives, an additional experiment was conducted [6]. Furthermore, the accuracy of Riera function was veri ied, showing reliable results in the event of impact accidents.…”
