What the study found
Sandwich panel anti-explosion performance is mainly influenced by several internal factors, including core characteristics, core combination, core thickness, front face sheet thickness, structural strength and stiffness, and interfacial bond performance.
Why the authors say this matters
The authors conclude that sandwich panels are an important route to lightweight structures with high anti-explosion performance. The study suggests that understanding material behavior and structural failure is needed to improve design and optimization.
What the researchers tested
The article reviews research progress on anti-explosion performance and optimization design methods for sandwich panels in multiple explosion scenarios. It discusses how sandwich panels absorb energy through core plastic deformation and panel bending and stretching, and it considers the links between material properties, failure mechanisms, and structural response.
What worked and what didn't
The abstract reports that core characteristics, core combination, thickness of the core and front face sheet, strength and stiffness, and interfacial bond performance are the main internal factors affecting dynamic response and anti-explosion performance. It states that interfacial bond performance has a great influence on anti-explosion performance.
What to keep in mind
The abstract says the relationship between anti-explosion performance and material properties remains unclear, and it notes a lack of research on material failure mechanisms. It also says that limited multi-factor collaborative analysis restricts conclusions and optimization, but it does not provide detailed limitations beyond that.
