Special Issue Information

Dear Colleagues,

In the dynamic realm of materials science, computational material modeling has emerged as a cornerstone, significantly propelling our understanding and innovation in the behavior of materials, particularly in terms of structure analysis, physical properties, and underlying mechanisms. This domain, intrinsically interdisciplinary, marries theoretical predictions with practical applications, notably in electronic structures, material prediction, and material application prediction.

The exploration of electronic structures through computational methodologies has unfolded vast possibilities, from understanding the quantum behaviors of materials to manipulating these very properties for tailored applications. These explorations have not only enriched our knowledge base but have also paved the way for novel materials and unforeseen technological advancements. Furthermore, the predictive modeling of materials, empowered by computational prowess, has revolutionized material discovery and design. This predictive capacity is particularly transformative in industries where new materials with specific properties—be they related to strength, conductivity, or durability—are constantly in demand.

Moreover, the sphere of material application prediction is experiencing a renaissance, attributable to the predictive insights offered by computational material science. These predictive endeavors extend beyond mere theoretical speculation, offering tangible, impactful foresights into materials' behavior and integration in real-world applications. This is especially salient in sectors such as aerospace, microelectronics, and renewable energy, where the performance of materials can make or break technological feasibility and efficiency.

However, the journey does not end with prediction; understanding the fundamental mechanisms through comprehensive computational studies empowers researchers to not only anticipate material behavior but also manipulate and optimize materials for desired functions. This deep dive into the mechanistic world of materials, from atomic interactions to macroscopic properties, is quintessential for innovation and the forward trajectory of materials science.

As the field of computational materials science is rapidly evolving and expanding its horizon, it is critical to provide a platform for the dissemination of groundbreaking research, insightful reviews, and spirited scientific discussions. Therefore, it is with great enthusiasm that I invite you to contribute your valuable research findings, insights, and reviews to this Special Issue focusing on "Materials Modeling: Structure Analysis, Physical Properties and Mechanisms". Your contributions will undoubtedly enrich the scientific community's collective knowledge and spur further innovations in this vibrant field.

We eagerly anticipate your manuscripts, be they full papers, communications, or reviews, each poised to add a unique facet to this complex, ever-evolving scientific mosaic.

This study investigates the thermal stress and bolt load distribution in a hybrid panel structure of an aircraft mechanical joint under extreme temperatures. The hybrid panel structure comprises two aluminum alloy splices, six T-shaped composite stringers, and two composite skins, secured together with 96 bolts. This study analyzed the strain induced by thermal stress on composite materials and metals within the structure across temperatures, employing temperature environment tests ranging from room temperature to −54 °C, alongside a carrying capacity test at −54 °C. Furthermore, a three-dimensional simulation model of the panel structure was developed, incorporating considerations for contact, metal elastoplasticity, and the progressive damage failure of composite materials. This model facilitated the determination of thermal stress and bolt load distribution patterns. The results indicate a strong consistency between the finite element analysis outcomes and the experimental data. Temperature variations exacerbate the uneven distribution of bolt loads, concentrating the load near the edges of the hybrid structure while diminishing it in the center. The bolt load distribution parallel to the mechanical load direction forms an “M” shape, with a maximum load magnitude of approximately 31 kN. Perpendicular to the mechanical load, the bolt load undergoes significant changes, especially at the edges, reaching a maximum of about 20 kN, which warrants attention. The bolt-load distribution of the structure with the increase in mechanical load at −54 °C tends to be consistent with that at room temperature. Full article
