Finite element simulation of reinforced concrete slabs under impact loading
In a few years ago, efforts for assessing and predicting the behaviour of concrete structures subjected to impact loads have been hampered by lack of adequate computational procedure and unavailability of good quality experimental results. Furthermore, computer software was also not yet developed...

| description |
In a few years ago, efforts for assessing and predicting the behaviour of concrete
structures subjected to impact loads have been hampered by lack of adequate
computational procedure and unavailability of good quality experimental results.
Furthermore, computer software was also not yet developed up to the standards of
today. Nowadays, the numerical models for the impact load assessment are starting
to become more accurate and reliable. Combined with modern computer hardware,
the computational time for such an assessment has been reduced to a satisfactory
level. In this study, an attempt has been made to examine the accuracy of modern
software with regards to assessing the response of reinforced concrete slabs subjected
to impact loading near the ultimate load ranges. The response such as Time-Impact
force graph, damage wave propagation, failure process of steel reinforcement,
effectiveness of mesh density, effect of projectile size and final crack pattern are
verified against existing experimental results. It is shown that the present general
purpose finite element software is able to simulate and predict the structural
behaviour satisfactorily. |
