Special Issue Information

Dear Colleagues,

Metals, composites, and ceramics are functional materials found in nature or synthesized for use in the design of structural components to bear static and dynamic loads. Under extreme conditions, such as ballistic impacts, thermal shocks, or excessive loading, materials and structures respond differently to the loading state and loading rate. Phenomena such as fracture, dislocation dynamics, and viscoplasticity emerge due to these extreme conditions and substantially affect the strain–stress response, energy absorption, and crashworthiness of materials and structures. A thorough understanding of these phenomena requires testing, simulation, and analyses.

This Special Issue is concerned with the responses of structures and materials subjected to impact and high-rate loading. Scientifically sound and well-organized analytical, computational, and experimental studies are being solicited. Subjects relevant to this Special Issue include the following topics and those associated with them: the behaviour and failure of structures and materials under impact loading, the structures and materials used to protect and absorb impact loading, dynamic behaviour, and the failure of materials including plasticity and fracture, structural crashworthiness, high-rate mechanical and forming processes, impact and high-rate loading/measurement techniques and their applications, mesoscale modelling, and constitutive models for materials under impact loading.

Manuscripts submitted for publication will be subjected to stringent peer review and assessed for their contribution to scientific understanding of both these phenomena and the responses of structures and materials to impact and high-rate loading. Well-designed and well-documented experimental studies that advance knowledge of the responses of materials and structures subjected to impact and high-rate loading are of relevance and interest. However, they should be accompanied by an analysis of the experimental data and appropriate conclusions. The inclusion of analytical modelling and/or numerical simulations to support the experimental findings will enhance the depth and quality of the research reported.

The use of thin-ply composite materials has rapidly increased due to their tailorable mechanical properties and design flexibility. Considering an adhesively bonded composite joint, peel stress stands out as a key contributor leading to failure among other primary stress factors. Therefore, the reinforcement of carbon fiber-reinforced polymer (CFRP) laminates throughout the thickness could be considered as an approach to improve the joint strength. Using thin plies locally between the conventional CFRP layers in a laminate can enhance the strength, as the sudden change in stiffness means that the load transfer is not monotonous. Consequently, the following study examined the effect of altering thin plies gradually throughout the thickness on the behaviour of the CFRP laminates when subjected to transverse tensile loading. To achieve this goal, the CFRP laminates were gradually modified by using different commercially accessible prepreg thin plies, leading to an improved overall structural performance by reducing stress concentrations. Besides conducting an experimental study, a numerical assessment was also carried out utilizing Abaqus software with a Representative Volume Element (RVE) at the micro scale. The comparison of reference configurations, which involved various thin plies with different thicknesses and traditional CFRP laminates, with the suggested gradual configuration, demonstrated a notable enhancement in both strength and material cost. Furthermore, the proposed RVE model showed promising capability in accurately forecasting the strength of fabricated laminates. Full article
