Explosion mechanics has evolved far beyond its origins in explosives and defense engineering, according to a new roadmap published in Theoretical and Applied Mechanics Letters (TAML). The comprehensive document, spanning 65 sections, brings together 175 researchers from 90 institutions to present a unified view of how matter, materials, and engineering systems behave under extreme dynamic loading.
At its core, explosion mechanics investigates how high-power-density energy is transmitted through shock waves and other intense dynamic processes within extremely short timescales, leading to high-speed flow, large deformation, and material failure. The roadmap emphasizes that the field is transitioning from solving specific engineering problems to becoming a broader science of matter and engineered systems under extreme conditions. This shift requires combining advanced experiments, theoretical models, and computational simulations to capture ultrafast events and highly nonlinear, multiscale behaviors.
One of the major challenges identified is the integration of artificial intelligence into mechanics research. The authors frame this as a paradigm shift comparable to Galileo's experiment-and-mathematics approach, moving toward AI-empowered scientific discovery. The key question is not whether data-driven methods can replace physical models, but how experimental evidence, mechanics-based understanding, numerical simulation, and AI can work together to improve prediction of complex extreme processes. This integration is seen as essential for tackling strongly nonlinear and multiscale problems that traditional approaches struggle with.
The implications extend well beyond conventional explosion scenarios. Insights from shock waves, high-speed impact, and dynamic material failure are increasingly relevant to aerospace engineering, advanced manufacturing, and structural protection. A companion Perspective in TAML highlights how knowledge of extreme loading and structural failure can help design resilient infrastructure that not only resists severe events but also maintains and recovers functionality. This broader relevance underscores the roadmap's timeliness in connecting advances across disciplines and identifying shared scientific challenges.
Explosion mechanics has a distinctive history in China, where Hsue-Shen Tsien (Qian Xuesen) introduced the term in 1963 during the "Two Bombs and One Satellite" program. Over six decades, it has grown into an interdisciplinary field spanning fluid mechanics, solid mechanics, physics, and chemistry. The new roadmap provides a shared reference point for future research, consolidating current knowledge, open questions, and emerging tools. The full roadmap is available via DOI 10.1016/j.taml.2026.100714.
For researchers and engineers, this roadmap signals a shift toward more integrated, AI-enhanced approaches that could accelerate breakthroughs in materials science, protective structures, and energy transmission. As extreme dynamic conditions become more relevant across industries, the collaborative framework established here may drive innovation and improve safety in applications ranging from aerospace to infrastructure. The involvement of 175 researchers from 90 institutions highlights the global effort to advance this critical field.
