Thios research equipment award will assist in the procurement of mechanical loading systems for the application of time-dependent biaxial loading. The equipment involved consists essentially of two independent load actuators to apply forces in the x and y direction with independent servo controllers on each axis. The actuators are restrained by a hexagonal loading frame. This equipment will be utilized to study the behavior of composite materials under biaxial states of stress. Research plans include studies of polymers-matrix composites (silicon ccarbide in titanium and graphite in aluminum). Studies of these materials will focus on non-linear deformation, static failure criteria, delamination, damage initiation and growth, and compressive stability.

THOS研究设备奖将帮助采购机械加载系统，用于随时间变化的双轴加载应用。所涉及的设备基本上由两个独立的负载执行器组成，在x和y方向上施加力，每个轴上都有独立的伺服控制器。执行机构由六角形加载框架约束。该装置将用于研究复合材料在双轴应力状态下的行为。研究计划包括研究聚合物基复合材料(钛中的碳化硅和铝中的石墨)。对这些材料的研究将集中在非线性变形、静态破坏准则、分层、损伤的形成和发展以及压缩稳定性方面。
