| 概要 | Recently, consideration of high velocity flying object impact for infrastructure is needed in order to protect human life from natural disasters due to tornadoes or volcanic eruptions. Although many e...xperiments on the impact strength of concrete structural members have been performed so far, prediction of local failure such as penetration or scabbing of concrete caused by high velocity flying object impact is still difficult and inaccurate. Hence, Smoothed Particle Hydrodynamics (SPH) Method is applied to simulate the local failure of concrete stractural members (beam and slab). At first, the accuracy of SPH analysis is confirmed by elastic plastic behavior of RC beam under low speed impact load. After that, penetration failures of concrete slab under high speed impact are simulated and discussed the penetration failure limit of concrete slab using analyses results.続きを見る |
