| Summary: | This paper presents a simple and reliable non-linear numerical analysis incorporated
with fully Lagrangian method namely Smoothed Particle Hydrodynamics (SPH) to predict the
impact response of the reinforced concrete (RC) beam under impact loading. The analysis
includes the simulation of the effects of high mass low-velocity impact load falling on beam
structures. Three basic ideas to present the localized failure of structural elements are: (1) the
accurate strength of concrete and steel reinforcement during the short period (dynamic), Dynamic
Increase Factor (DIF) has been employed for the effect of strain rate on the compression and
tensile strength (2) linear pressure-sensitive yield criteria (Drucker-Prager type) with a new
volume dependent Plane-Cap (PC) hardening in the pre-peak regime is assumed for the concrete,
meanwhile, shear-strain energy criterion (Von-Mises) is applied to steel reinforcement (3) two
kinds of constitutive equation are introduced to simulate the crushing and bending cracking of
the beam elements. Then, these numerical analysis results were compared with the experimental
test results. |
