multi-axial loading

设计用于拉伸/压缩和扭转加载的双轴机械测试框架将使用最先进的控制和软件进行修改，以实现对工程材料单轴或组合轴加载中的应力、应变和应变率的精确控制和测量。联合收割机加载的能力将使新的研究演变的微观结构，其特征在于在制造中使用的复杂形状变化操作中观察到的各向异性机械行为。将机械响应耦合到应力和/或应变状态将用于开发对变形处理和/或材料行为进行建模所需的本构关系，所述材料行为用于产品，例如用于汽车的框架管、用于核工业的压力管以及用于人骨置换的人造或天然材料。

A two-axis mechanical testing frame designed for tension/compression and torsion loading will be modified with the state of the art controls and software to enable precise control and measurement of stress, strain, and strain rates in single or combined axis loading of engineering materials. The ability to combine loading will enable new study of the evolving microstructure characterized by anisotropic mechanical behaviour observed in complicated shape change operations used in manufacturing. Coupling of the mechanical response to the stress and / or strain state will be used to develop constitutive relationships necessary for modelling deformation processing and, or material behavior in service of products such as frame tubes used in automobiles, pressure tubes used in the nuclear industry, and artificial or natural materials used for human bone replacement.
