Explosion mechanics has long been associated with explosives, shock waves and defense engineering. But a new field-wide roadmap published in Theoretical and Applied Mechanics Letters (TAML) argues that the discipline has outgrown that narrow identity and now stands as a broader science of how matter and engineered systems respond under extreme dynamic conditions.
The Explosion Mechanics Roadmap, developed by 175 researchers from 90 institutions, spans 65 sections covering energetic materials and detonation, shock waves and impact dynamics, damage and protection, and related engineering applications. Its central scientific question is how a medium behaves when energy loading, strain rates and deformation are pushed to their limits—processes that unfold in extremely short times and trigger high-speed flow, large deformation and material failure.
Answering that question requires combining experiment, theory and computation, from advanced measurements that capture ultrafast events to models that describe highly nonlinear, multiscale behaviors. The roadmap’s authors say the field is moving beyond solving specific engineering problems and becoming a wider science of matter and engineered systems under extreme conditions, making a shared reference point especially timely.
One of the roadmap’s most significant contributions is its framing of a paradigm shift in how mechanics research is conducted—from Galileo’s experiment-and-mathematics approach to AI-empowered scientific research. The authors stress that the real 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. That integration is identified as one of the field’s major challenges, particularly for strongly nonlinear and multiscale problems.
The implications extend well beyond traditional explosion problems. 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 focuses on resilient infrastructure, showing how knowledge of extreme loading and structural failure can help not only resist severe events but also maintain and recover engineering functionality.
The roadmap also traces the field’s distinctive history in China. Hsue-Shen Tsien (Qian Xuesen) introduced the term “explosion mechanics” in 1963 during the country’s “Two Bombs and One Satellite” program. It grew into an interdisciplinary field spanning fluid mechanics, solid mechanics, physics and chemistry. Six decades on, its scope has widened from individual explosion events to a broader scientific challenge: understanding and predicting how matter and engineered systems respond under extreme dynamic conditions.
The full roadmap is published with DOI 10.1016/j.taml.2026.100714. By consolidating current knowledge, open questions and emerging tools in a single field-wide view, the authors aim to give researchers a common reference point for the road ahead—one that balances physical understanding with the growing role of AI.
