Explosion mechanics has long been associated with explosives, shock waves, and defense engineering. But a new roadmap published in Theoretical and Applied Mechanics Letters (TAML) signals that the field has expanded far beyond its traditional boundaries. The Explosion Mechanics Roadmap, developed by 175 researchers from 90 institutions, spans 65 sections and reviews advances in energetic materials, detonation, shock waves, impact dynamics, damage and protection, and related engineering applications. Its publication matters because it provides a shared reference point for a discipline that now touches aerospace engineering, advanced manufacturing, and structural protection—areas where understanding extreme loading and material failure is critical.
At its core, explosion mechanics asks how high-power-density energy is transmitted through shock waves and other intense dynamic processes within extremely short times, triggering high-speed flow, large deformation, and material failure. This raises a fundamental scientific question: how does a medium respond when energy loading, strain rates, and deformation are pushed to their limits? Answering it requires integrating experiment, theory, and computation, from advanced measurements that capture ultrafast events to models and simulations that describe highly nonlinear, multiscale behaviors. The roadmap’s comprehensive scope makes it especially timely, as it connects advances across these domains and identifies shared scientific challenges.
The roadmap also highlights a broader shift in how mechanics research is conducted. It frames the transition from Galileo’s experiment-and-mathematics paradigm to AI-empowered scientific research as one of the field’s major challenges. The 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 particularly important for strongly nonlinear and multiscale problems, where purely empirical or purely theoretical approaches fall short.
Beyond traditional applications, insights from shock waves, high-speed impact, and dynamic material failure are increasingly relevant to resilient infrastructure. A companion Perspective in TAML shows how knowledge of extreme loading and structural failure can help not only resist severe events but also maintain and recover engineering functionality. This broader relevance underscores why the roadmap matters: it positions explosion mechanics as a science of matter and engineered systems under extreme dynamic conditions, with implications for safety, sustainability, and innovation.
The field has a 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 new roadmap, detailed in the DOI 10.1016/j.taml.2026.100714, gives the field a shared reference point for what comes next, bringing together current knowledge, open questions, and emerging research tools in a single field-wide view.
