Special Issue Information

Dear Colleagues,

Additive manufacturing technology is a revolutionary technology that integrates digital manufacturing, intelligent manufacturing, and green manufacturing. It has the advantages of high design flexibility, low material waste, and strong personalized customization, which can significantly shorten the development cycle of products. It has been widely used in multiple fields, including automotive, medicine, aerospace, electronics, etc. Additive manufacturing technology has injected inexhaustible vitality into metal structural materials. Complex additive manufactured metal structural materials can be customized and evaluated, which will promote the rapid development of social economy and key industries.

In this Special Issue, we welcome articles that focus on the design, characterization, and evaluation of additive manufactured metal structural materials. Theoretical analysis, experimental tests, and numerical simulations are all welcome. Contributions to this Special Issue are highly valued and appreciated. We invite you to contribute research work and reviews that relate to the benefits of additive manufactured metal structural materials in today's world.

Uniform and graded BCC lattice cylindrical shells were proposed, and the corresponding structural specimens were fabricated with 316L stainless steel material. Experimental testing and numerical simulations were both utilized to investigate the quasi-static and dynamic compression behavior of the uniform and graded BCC lattice cylindrical shells. Finite element results were compared with the experimental results. Parametric studies were conducted to study the effects of relative density, gradient distribution, and loading velocity on the mechanical properties and deformation features. When the relative density increased from 9% to 25%, a 175% increase in SEA could be seen. Graded BCC lattice cylindrical shells almost exhibited the same mechanical performance. When compared with the SEA value under low-speed loading conditions, a 26.95% maximum increase could be witnessed in the graded-5 specimen under high-speed loading. Testing results indicated that the proposed uniform and graded BCC lattice cylindrical shells exhibited fascinating quasi-static and dynamic mechanical behavior, which provided guidance for the design and application of next-generation lightweight materials with excellent protective properties.
