Controlling the Load Distribution in High-Strength Materials Army Science Planning and Strategy Meeting (ASPSM)
Abstract
Future Army capabilities require understanding and controlling the physics associated with material fracture and failure from applied loads, a mechanical behavior relevant to many problems within Army systems, ranging from bolted joints to armor, and one that impacts Soldier lethality and survivability. To address this, the US Army Combat Capabilities Development Command Army Research Laboratory held an Army Science Planning and Strategy Meeting (ASPSM) on Controlling the Load Distribution in High-Strength Materials in December 2020. Participants presented and discussed material concepts for redistributing localized loading and delay or preventing failure due to impact in granular media, lattice structures, and emerging composite architectures. Leveraging the researchs inherently interdisciplinary nature (material science, experimental and computational mechanics, machine learning, and computer science), participants identified a need for developing numerical techniques to model the constitutive response of these materials, including mechanical behavior under large deformations, fracture, and failure. Machine learning algorithms can offer some advantages in speed and accuracy by integrating into the data-driven design strategy, but their application needs to be validated by experimental data or physics-based models. A research strategy focused on these principles will produce systems and equipment for the future Soldier with an enhanced capability for mitigating stresses generated from impact or other sources.
