Simulation five point bending of a composite concrete beam(NSC+UHPFRC) in Abaqus

In this tutorial, the Simulation five point bending of a composite concrete beam(NSC+UHPFRC) in Abaqus has been done. The normal strength concrete beam as a cover is modeled as a three-dimensional solid part. The Ultra-High-Performace-Fiber-Reinforce-Concrete core is modeled as the a three-dimensional solid part. The steel bars and strips are modeled as three-dimensional wire part. You can see a figure of the assembled parts below

Ultra-high performance fiber-reinforced concrete (UHPFRC) is a cementitious material produced with Portland cement, pozzolans, small size aggregates, inert fillers, superplasticizer, and surface-treated steel fibers, although UHPFRC is more costly than NSC, its improved structural properties usually decrease the material consumption, reinforcement ratios, maintenance costs and increase the service life

Concrete damage plasticity material model represents a constitutive model which is based on a combination of theory of plasticity and theory of damage mechanics. This material model is often used in solving geotechnical problems due to its realistic description of mechanical behavior of concrete material. The data of the CDP mode is extracted form the reference paper. This model consider the tension and compression damage for both concrete types. The steel material with elastic plastic model is considered for the steel reinforcements. to model the solving procedure, both static and dynamic approach can be selected. In this tutorial the dynamic explicit step to reduce the time of the simulation is used. The proper interactiona nd boundary is assigned to the all pars. The mesh should be fine to obtain correct results

After the simulation, all results such as stress, strain, damage, failure, force-displacement diagram, and … are available. You can see some figures for the results below
