The simulation of high rate impact tests on composite structures with mixed finite element type analysis
The simulation of high rate impact tests on composite structures with mixed finite element type analysis
To reduce the cost of modelling large composite structures under impact loading, a mixed finite element type analysis, involving solid elements, thin shell elements and their coupling has been developed. Simulation has been carried out in LS-DYNA for projectile impact on plain weave composite plates and a large composite aero engine casing ring. Compared to the models with solid elements only, this method provided similar prediction in terms of projectile trajectory, target deformation and material failure. When a quarter of the casing ring was model with solid elements and three quarters with shell elements, this method required only 50% of the computational resources and time used in the all-solid-element approach.

Abstract
To reduce the cost of modelling large composite structures under impact loading, a mixed finite element type analysis, involving solid elements, thin shell elements and their coupling has been developed. Simulation has been carried out in LS-DYNA for projectile impact on plain weave composite plates and a large composite aero engine casing ring. Compared to the models with solid elements only, this method provided similar prediction in terms of projectile trajectory, target deformation and material failure. When a quarter of the casing ring was model with solid elements and three quarters with shell elements, this method required only 50% of the computational resources and time used in the all-solid-element approach.
