Abstract
This review provides an overview of experimental impact testing and numerical impact simulations for composite materials in terms of a complementary combination of both techniques. It discusses the significance of impact testing, describes experimental methods, such as drop-weight testing, pendulum testing, and ballistic testing, and explains numerical alternatives including finite element analysis. Relevant standards for impact testing are outlined, and a comparison of experimental and numerical research findings is presented. It highlights that numerical simulations are cost-effective and efficient for initial composite material development and prototype stages of structures, but may be less accurate compared to experimental approaches. Experimental testing is recognised for providing more accurate results, although it can be time-consuming and costly. The importance of a combined approach is emphasised to demonstrate that numerical simulations complement experimental testing and vice versa to obtain a comprehensive understanding of composite material behaviour under impact. This integrated approach can ensure safer and more efficient use of composite materials in demanding applications, contributing to the prevention of failures and improvement of the reliability of composite structures.
