项目摘要
Particulate materials remain a class of materials not mastered with regard to modeling computationally their spectrum of mechanical behavior in a physically-based manner across several orders of magnitude in length-scale. Particulate materials may transition in an instant from deforming like a solid to flowing like a fluid or gas and vice versa. It is not feasible to simulate computationally the heterogeneous, localized deformation, and flow response in the engineering application of interest involving particulate materials using a pure particle-based materials modeling approach (such as DEM).Intellectual merit: The project seeks to overcome this limitation in scale-representation of particulate materials by the development of a computational multiscale modeling approach and its calibration/ validation against micro to macro-scale experiments. In doing so, the proposed effort will 1) provide physical insight into the deposition and compaction of metallic powders into complex die shapes and the potential mechanisms leading to non-uniform density after compaction; and 2) determine the redistributed state of sand particles in the vicinity of a rigid penetrating object.Broader impacts include (i) transfer of innovative computational multiscale modeling technology to the automotive industry through CAVS for improving the manufacture of near net-shape components of extremely complex geometries and various unforeseen alloy material systems; (ii) recruitment of underrepresented minorities in the engineering disciplines; and (iii) sharing of experimental and computational advances and physical insight gained with the technical and student communities.
颗粒材料仍然是一类没有掌握的材料,关于以基于物理的方式在长度尺度上的几个数量级上对其力学行为谱进行计算建模。 颗粒材料可以在瞬间从像固体一样变形转变为像流体或气体一样流动,反之亦然。 在工程应用中,用纯颗粒材料模型方法来模拟颗粒材料的非均匀、局部变形和流动响应是不可行的(如DEM)。智力优点:该项目旨在通过开发计算多尺度建模方法及其校准来克服颗粒材料尺度表示的限制。验证微观到宏观尺度的实验。 在这样做时,所提出的努力将1)提供对金属粉末沉积和压实成复杂模具形状以及导致压实后不均匀密度的潜在机制的物理洞察;(2)确定刚性穿透物体附近沙粒的重新分布状态。更广泛的影响包括(i)通过CAVS将创新的计算多尺度建模技术转移到汽车行业,以改善极其复杂几何形状和各种不可预见合金材料系统的近净形部件的制造;(ii)在工程学科中招聘代表性不足的少数群体;(iii)与技术界和学生界分享实验和计算方面的进展以及获得的物理见解。
