“…These impacts can be classified as low‐velocity impacts, debris‐flow impacts and high‐velocity impacts. Detailed research on PUF sandwich composites has been carried out in previous years to study their impact behavior using different numerical, analytical and experimental techniques . Sadighi and Pouriayevali studied the low‐velocity impact of PUF sandwich beams using indentation theory and Finite Element Analysis (FEA).…”

Sandwich composites with a polyurethane foam (PUF) core have become a versatile set of materials with applications ranging from basic construction elements to advanced engineering materials. This diverse range of applications has provided these sandwich materials with a distinctive position in today's engineering world. This review focuses on the broad research that has been carried out on PUF core‐based sandwich composites over the years—especially in the last decade. Thorough details have been presented focusing on basic PUF core sandwich structures, advanced PUF core sandwich composites with different kinds of reinforcements and complex structures such as hybrid sandwich panels. All the research presented here has been categorized carefully, such as the types of materials used in various studies, the types of reinforcements and testing techniques used, including mechanical, electrical, dynamic, thermal and acoustic methods etc. Comparisons have also been made based on similar materials, similar testing procedures and similar application areas. Research areas have been highlighted by giving a deep insight into the most promising research, manufacturing techniques and improvement procedures. Major consumption areas and application sectors for PUF core sandwich composites have also been discussed in this review. Finally, conclusions have been made based on the results found from a literature investigation.

“…The semi-continuous model, developped in the research team for woven laminates subjected to impact loadings, has been already presented in the articles [25,26,27,28]. The modelling of the woven ply decouples the resin and tows behaviour to represent simultaneously the damaged resin and the undamaged fibers tows.…”

This article concerns the modelling of post-impact damage propagation in thin woven composite laminates. Simulations of low velocity impacts and post-impact quasi-static tension are performed on single-material and hybrid laminates. The modelling is based on the semi-continuous approach implemented into the explicit finite element code RADIOSS. The bundles are modelled with rod elements and a specific damageable shell element is used to stabilize this truss structure. Improvements are brought with the introduction of a compressive failure criterion for the rod elements and the development of a pseudo-plastic law with damaging for in in-plane shear. The results provided by the modelling well correlates the experimental observations in terms of damage propagation and load-displacement curves for all the configurations studied.

“…Wisnom [25] and Abrate [26] have provided detailed reviews on the use of cohesive zone interface elements to model matrix failures in polymer composites. Another modelling strategy is the Semi-Continuous approach [27,28,29,30,31,32]. Damage mechanisms in woven and unidirectional laminates under low and medium velocity impacts are well predicted.…”

This paper deals with low velocity and medium velocity impacts on thin carbon/epoxy hybrid laminates made of unidirectional plies and woven fabric layers. Drop weight and gas gun impact tests were performed to compare the damage mechanisms of thin hybrid laminates with those of woven laminates of equivalent stiffness and mass. The results show that hybrid laminates present a better impact behaviour in terms of post impact damage extent. These tests were then modeled using a semi-continuous approach. The numerical results well correlate the experiments.
