In this tutorial, the Simulation high-velocity impact of the steel projectile on the composite panel(Steel-Concrete-Epoxy glass) in Abaqus has been investigated. The steel projectile is modeled as a cylindrical solid part. The steel plate as a first layer of the panel is modeled as a three-dimensional part. The concrete as a middle plate of the panel is modeled as a three-dimensional solid pat and the composite layers are modeled as three-dimensional part with continuum shell technique. The beam part is modeled as the wire part. You can see figures of the assembled parts at below
The steel material with elastic-plastic behavior is used for the projectile and the first layer of the panel. Ductile and shear damage criteria to predict damage propagation and failure are used. The elastic behavior with fail stress for the epoxy-glass lamina is used. To consider damage in the composite layouts, Hashin’s damage criterion with damage evolution is used. To model concrete behavior under the high-velocity impact, the JH2 material model as the input file is used. This material model can calculate the damage and failure in the brittle material properly.
The dynamic explicit step with a general contact procedure is used. The contact between steel plate and concrete, concrete and the first layer of the composite is assumed as perfect contact. The cohesive interaction base on the cohesive surface as contact property with damage data is used among the composite layouts. The beam part is embedded inside the concrete host. The Symmetry boundary is implied for the symmetry surfaces and fixed boundary for the sides of the panel. The initial velocity is assigned to the steel projectile. The mesh should be fine to obtain good results
After the simulation, all results such as stress, strain, damage parameters, and failure….are obtainable. You can see some figures for the results below
