Summary: Polymer-based sandwich composites are increasingly used in the marine industry and face the risk of encountering high-intensity underwater or in-air explosive loading. This review discusses achieving blast mitigation with polymeric composites and highlights the differences in loading mechanisms between AIREX and UNDEX. Understanding these mechanisms facilitates tailored design approaches for blast mitigation, with recent research on composite sandwich architecture and other foam metamaterial constructions also addressed.

Summary: This study aims to explore the dynamic crushing behaviors of sandwich structures made of UHPFRC face sheets and steel and PU foam cores. Impact tests were performed on 12 sandwich structure specimens, and the force profiles of EF and HT types exhibited low peak impact force and high plateau force. The results showed that the polyurea sprayed on the UHPFRC face did not affect the crashworthiness, and increasing core thickness improved mean crushing force. The FE models validated the strong energy absorption stability of EF and HT structures, and the multi-objective optimization suggested that the HT-F structure is more suitable for practical applications.

Summary: With the development of composite structures, polyurea elastomer can be used to enhance the protective performance of composite laminated structures. A study was done on the blast resistance of CFRP/polyurea composite plates using a 3D-DIC full-field measurement method. The results showed that the polyurea coating on the rear surface of CFRP exhibited superior blast resistance, while the deformation level of the composite plates increased with the decrease of scaled distance.

Summary: In this paper, a composite reinforced hyper-elastic porous polyurethane structure filled with carbon fiber composite circular tubes is designed and fabricated. The dynamic responses and failure modes of the structure under underwater blast loads are investigated through tests and simulations. The results show that adding composite tubes significantly improves the stiffness and energy absorption capacity of the structure. The CRHPPs without reinforcement in the front first layer, whether gradient or uniform in the other layers, show better underwater explosion resistance and protection effect.

Summary: This study focuses on proposing new theories and models to analyze the transient response of elastoplastic sandwich beams in underwater blast, aiming to gain more understanding of the propagation and dissipation of underwater blast waves and optimize the design of sandwich structures with excellent underwater blast resistance. By integrating rarefaction-wave-related terms into the structural damping matrix, the analysis of underwater blast is transformed into the dynamic response of sandwich structures. The core elastic modulus is found to dominate the impulse transmitted to the sandwich structure, while the core strength and strain hardening govern the pressure delivered to the supports.

Summary: The direct impact method provides a higher sample deformation rate and reliable results for materials with low yield strength and hardening rate. This study proposes an alternative procedure for calculating the strain rate in order to improve accuracy of the direct impact method for a wide range of metals and alloys. The proposed method has been validated through finite element analysis and direct impact tests, and it qualitatively changes the shape of the stress-strain curve by adding an unloading area.

Summary: This study investigates the dynamic bifurcation of a column when it impacts a rigid plane vertically, which is different from the classical Eulerian static buckling. The findings show that either the dimensionless critical buckling time or the dimensionless critical buckling velocity can be used to determine whether buckling has occurred. Different dimensionless initial defects in the column result in different dimensionless displacement responses, and the nonlinear effect influences the analysis results.

Summary: This study investigated the impact of spherical foreign objects on simulated blade edges through experimental and theoretical analysis. The experimental results showed that increasing impact energy resulted in larger damage sizes, and three distinct types of deformations were observed in FOD. Accurate FOD prediction models were developed using linear and power formulas. The theoretical analysis using a spring-mass system based on Winkler's elastic-plastic foundation theory yielded results in good agreement with experimental measurements, providing a reference for fatigue life assessment of aeroengine blades.

Summary: This paper presents a multi-objective optimization procedure for effectively designing gradient lattice structures under dynamic loading. The aim is to maximize energy absorption characteristics and achieve a lightweight design. Through considering design variables such as the relative density and density gradient, the peak crushing force reduction and maximized specific energy absorption are simultaneously optimized. A simplified beam-based finite element model is used to efficiently model and simulate the lattice structures. An artificial neural network is trained to predict energy absorbing characteristics and find optimal lattice structure configurations. The network is trained using a multi response adaptive sampling algorithm, allowing parallel simulation with automatically generated finite element models. A multi-objective genetic algorithm is then used to find optimal combinations of design parameters for lattice structures under different impact velocities and cell topologies.
