Special Issue Information

Dear Colleagues,

The fracture mechanics of materials is an interesting research direction that studies how materials develop cracks under load and how these cracks propagate to ultimately fail. It is of great significance for engineering design, material selection, structural integrity assessment, and material life prediction. In terms of safety assessment, by understanding the principles of fracture mechanics, engineers can better predict the possible failure modes of materials or structures during use and take measures to prevent catastrophic failures. In terms of material selection and development, understanding the fracture behavior of different materials can help in selecting the most suitable material for specific applications. In terms of accident analysis and prevention, fracture mechanics acts as an analytical tool to determine the cause of material or structural failure, thereby improving future design and technical standards and avoiding similar accidents from happening again. Thus, the fracture mechanics of materials is crucial for ensuring the safe and reliable operation of engineering structures. It not only affects the success or failure of individual engineering projects, but also relates to the overall socio-economic development.

In this Special Issue, we welcome articles that focus on the fracture mechanics of materials and structures. Theoretical analysis, experimental tests, and numerical simulation are all welcomed. Contributions to this Special Issue are highly valued and appreciated. We invite you to contribute research work that relates to the benefits of the fracture mechanics of materials and structures in today's world.

A novel 316L stainless steel Vertex Modified BCC (VM-BCC) lattice unit cell with attractive performance characteristics is developed. Lattice structure, as well as the sandwich panel, are constructed. Numerical simulation is utilized to simulate the quasi-static compression, dynamic compression and blast behavior considering the rate-dependent properties, elastoplastic response and nonlinear contact. Finite element results are validated by comparing with the experimental results. Parametric studies are conducted to gain insight into the effects of loading velocity, equivalent TNT load and explosion distance on the dynamic behavior of the lattice pattern and sandwich panel. Testing results indicate that the proposed 316L stainless steel VM-BCC structure exhibits more superior plateau stress and specific energy absorption (SEA) than those of the BCC or Octet one. The proposed novel lattice will provide reference for improving the protective efficiency in key equipment fields and enhancing overall safety. Full article
