The central goal of this research is to reduce emission in transportation vehicles. Transportation vehicles account for close to 30% of air pollution in Canada. An active approach to reduce this pollution is electrification of vehicles. All major automotive manufacturer are planning to move toward electric vehicle and/or a mixture of electric and internal combustion hybrid vehicles. These emerging vehicles bring with them new design challenges that, in part, stems from new materials that are less known to automotive industry. Electrical steel is among those materials that are used in rotors and stators, main components of electrical engines. Due to the favorable magnetic properties, i.e., low iron loss and high permeability, electrical steels are preferred steel material widely used in construction of electrical engines. These steels come in the form of very thin sheets that are stacked to form a rotor or stator frame. Knowledge of their mechanical properties in the form of sheets and stacked laminates are of principal importance in design and manufacturing of electric engines and their long term durability. The proposed research studies the material and mechanical characteristics of a single sheet and stacked laminates under quasi-static and cyclic loads at room and elevated temperatures.

这项研究的核心目标是减少运输车辆的排放。在加拿大，运输车辆占空气污染的30％。减少这种污染的主动方法是车辆的电气化。所有主要的汽车制造商都计划朝着电动汽车和/或电燃烧混合动力汽车的混合物转向。这些新兴车辆带来了新的设计挑战，部分原因是新材料对汽车行业鲜为人知。电钢是用于转子和定子的材料之一，电动发动机的主要组件。由于有利的磁性特性，即低铁损失和高渗透性，因此电气钢被广泛用于电动机的构造中。这些钢的形式是非常薄的床单，这些材料被堆叠形成转子或定子框架。了解其机械性能的形式和堆叠层压板的形式在电动发动机的设计和制造及其长期耐用性方面至关重要。拟议的研究研究了单片板和层压板的材料和机械特性，在室内和温度升高的准静态和环状载荷下。
