首个公开的高爆炸药多材料冲击动力学数据集,用于训练AI模型模拟爆炸冲击过程。
The High Explosives and Affected Targets (HEAT) Dataset

- 基于洛斯阿拉莫斯实验室代码生成二维对称仿真数据,涵盖多种材料和复杂物理过程。
- 包含压力、密度、温度等时序场数据,覆盖冲击传播、塑性变形、动量传递等关键现象。
- 适合从事爆炸模拟、AI建模或多材料冲击研究的研究者使用。
人工智能代理模型为全物理仿真提供了计算高效的替代方案,但目前尚无公开数据集可用于训练和验证高爆炸药驱动的多材料冲击动力学模型。由于需要材料特定的状态方程(EOS)以及塑性、相变、损伤、流体不稳定性与多材料相互作用的模型,冲击传播模拟极具挑战性。爆炸驱动冲击还需反应材料模型来捕捉爆轰物理。为此,我们引入高爆炸药与受影响目标(HEAT)数据集,这是一个由洛斯阿拉莫斯国家实验室开发的欧拉多材料冲击传播代码生成的二维、柱对称仿真集合。HEAT包含两个部分:扩展冲击圆柱(CYL)仿真和扰动分层界面(PLI)仿真。每条记录包含热力学场(压力、密度、温度)、运动学场(位置、速度)及连续量如应力的时间序列。CYL部分覆盖多种材料,包括金属(铝、铜、贫铀、不锈钢、钽)、聚合物、水、气体(空气、氮气)以及炸药。PLI部分在固定材料组合下探索不同几何结构:铜、铝、不锈钢、聚合物和高爆炸药。HEAT捕捉了冲击传播、动量转移、塑性变形和热效应等关键现象,为多材料冲击物理的AI/ML模型提供基准数据集。
原文摘要 · Abstract (English)
Artificial Intelligence (AI) surrogate models provide a computationally efficient alternative to full-physics simulations, but no public datasets currently exist for training and validating models of high-explosive-driven, multi-material shock dynamics. Simulating shock propagation is challenging due to the need for material-specific equations of state (EOS) and models of plasticity, phase change, damage, fluid instabilities, and multi-material interactions. Explosive-driven shocks further require reactive material models to capture detonation physics. To address this gap, we introduce the High-Explosives and Affected Targets (HEAT) dataset, a physics-rich collection of two-dimensional, cylindrically symmetric simulations generated using an Eulerian multi-material shock-propagation code developed at Los Alamos National Laboratory. HEAT consists of two partitions: expanding shock-cylinder (CYL) simulations and Perturbed Layered Interface (PLI) simulations. Each entry includes time series of thermodynamic fields (pressure, density, temperature), kinematic fields (position, velocity), and continuum quantities such as stress. The CYL partition spans a range of materials, including metals (aluminum, copper, depleted uranium, stainless steel, tantalum), a polymer, water, gases (air, nitrogen), and a detonating material. The PLI partition explores varied geometries with fixed materials: copper, aluminum, stainless steel, polymer, and high explosive. HEAT captures key phenomena such as shock propagation, momentum transfer, plastic deformation, and thermal effects, providing a benchmark dataset for AI/ML models of multi-material shock physics.
