Special Issue Information

Dear Colleagues,

The Special Issue “Advances in Computation and Modeling of Materials Mechanics” aims to explore the forefront of research in the field of advanced material mechanics using theoretical computation and simulation techniques. This Special Issue focuses on investigating the mechanical behavior and properties of advanced materials at different scales, which have significant implications for various industries and applications, including aerospace, nuclear, automotive, and structural engineering. Therefore, the topics covers a wide range of research areas, including but not limited to the following: (1) Development and application of computational models and simulation methods for analyzing the mechanical properties of advanced materials; (2) Investigation of the mechanical response of advanced materials under different loading conditions, such as tensile, compressive, and shear forces; (3) Exploration of the relationships between the microstructure and mechanical properties of advanced materials; (4) Study of the effects of various factors, such as grain boundaries, defects, and interfaces, on the mechanical behavior of advanced materials; (5) Advancements in computational techniques for modeling and simulating the mechanical phenomena at different scales. The research published in this Special Issue will contribute to a deeper understanding of the mechanical behavior of advanced materials, facilitate the design and development of advanced materials with tailored properties, and foster interdisciplinary collaborations among researchers in the areas of materials science, nanotechnology, and computational mechanics. Original research papers, state-of-the-art reviews, communications, and discussions are welcomed.

The hot deformation behavior of titanium matrix composites plays a crucial role in determining the performance of the formed components. Therefore, it is significant to establish an accurate constitutive relationship between material deformation parameters and flow stress. In this study, hot compression experiments were conducted on a (2.5 vol%TiB + 2.5 vol%TiC)/TC4. The experiments were performed under temperatures ranging from 1013.15 to 1133.15 K and strain rates ranging from 0.001 to 0.1 s−1. Based on the stress–strain data obtained from the experiment, the constitutive models were established by using the Arrhenius model and the BP neural network algorithm, respectively. Considering the relationship between strain rate, hot working temperature, and flow stress, a comparative analysis was conducted to evaluate the prediction accuracy of two different constitutive models. The research results indicate that the flow stress of (2.5 vol%TiB + 2.5 vol%TiC)/TC4 increases with decreasing temperature and increasing strain rate, and the stress–strain curve shows obvious work hardening and softening behaviors. Both the Arrhenius model and the BP neural network algorithm are effective in predicting the hot compression flow stress of (2.5 vol%TiB + 2.5 vol%TiC)/TC4, but the average relative error and root mean square error of the BP neural network algorithm are smaller and the correlation coefficient is higher, thus possessing higher accuracy and reliability.
