衝突貫通後の速度予測のための鉄筋コンクリートの解析モデルの検討

抄録

A reinforced concrete model for impact simulation of a missile is studied. This concrete model is a hybrid model of solid elements and SPH (smooth particle hydrodynamics) elements, and solid elements turn into the SPH elements when the compressive strain 0.01 is satisfied. The residual speed of missile after perforation among simulation results is compared with, predicted results by empirical formula and test results which conducted in CRIEPI in 1990s, and it is shown that the simulation results are in good agreement with the test results rather than the predicted results by the formulae. This model can be used for an impact simulation of concrete structure with single or multiple walls in nuclear power plants.
