Numerical investigations of S-Glass/Polyester composite laminate plate under low energy impact

With the growing use of composites in military, air vehicles and naval structures, sporting goods and the power industry, the comprehension of impact mechanism and dynamic behavior is critical to composite designers and end users. A wealth of knowledge has been published on dynamic impact response of composite materials and structures. Yet, with continually emerging materials and processes, there is a lack of systematic structure-property-performance relationships that provide guidelines on the dynamic impact behavior of composites.The impact response of materials is generally categorized into low, intermediate, high or ballistic and hyper velocity regimes.The ability to predict the extent of damage and compression after impact of a composite structure can potentially lead to the exploration of a larger design space without incurring significant time and cost penalties. In this simulation Numerical investigations of S-Glass/Polyester composite laminate plate under low energy impact has been investigated. Conventional shell composite layout has been used to define composite layouts with different angles.You can see a figure of assemble parts of plate and projectile at below

Impact problems involve strong loading with a complex induced damage. To reproduce and hence analyse the complex phenomena occurring during the impact, numerical approaches are more adapted. The finite element method remains the most commonly adopted to simulate impact problems in various engineering fields. The Abaqus/Explicit FE code, with its dynamic explicit solver, is well suited for simulating such problems.The most commonly used in FE simulations of composite materials are layered shells, layered-solids, stacked solid elements and stacked or layered continuum shells.The plate is modelled with material as lamina with anisotropic elasticity coupled with Hashin’s damage criteria. There are interacting failures criteria where more than one stress component have been used to evaluate the different failure modes.During the impact the projectile with initial velocity cause a damage and stress in the composite plate which you can some figures of the results at below
