In this tutorial Low-velocity impact behaviour of RC slab strengthening with CFRP strips in Abaqus has been investigated.Reinforced concrete slabs are structural members that are com-monly used in constructions. Slabs are designed by considering the effects of both vertical static and dynamic loads. Impact load is a kind of impulsive dynamic load which is ignored in the design process of slabs like other structural members. The behaviour of rein-forced concrete slabs under impact loading is an area of research that is still not well understood; however, work in this area continues to be motivated by a broad range of applications. Examples include reinforced concrete structures designed to resist accidental loading scenarios such as falling rock impact; vehicle or ship collisions with buildings, bridges, or offshore facilities; and structures that are used in high-threat or high-hazard applications, such as military fortification structures or nuclear facilities. As a result, considerable work has been undertaken in an effort to develop impact-resistant design procedures and to improve the performance of reinforced concrete structures subjected to impact loads .
The concrete slab is modeled as three dimensional part with CDP material model and the CFRP is modeled as three dimensional shell part with elastic property couple with Hashin’s damage and the bars are modeled as wire part with elastic plastic material model. You can see a figure of the assembled parts at below
Dynamic explicit step with surface to surface contact has been implied. The contact between concrete and CFRP is considered as perfect contact and embedded region constraint is used for the bars inside the concrete host. The fixed boundary conditions assigned to the slab and initial velocity has selected for the rigid body. The mesh has good effect over the tensile and compressive damage propagation and other results. You can see some figures of the simulation at below
