Mechanics of Materials

实际工程材料，如金属，是复杂的、不均匀的晶体或颗粒的集合。这些颗粒根据取向和环境的不同具有不同的行为。虽然对于实际应用(例如汽车零部件的设计)，材料在应力下的响应通常被忽略这些影响来估计，但如果不考虑固有的不均匀的局部特征，则无法理解许多行为方面。我的研究着眼于局部不均匀和由此产生的内应力对材料变形的影响，以及在应力和温度波动下发生的过程。该研究对理解变形、发展实用工程技术和构件设计具有重要意义。

Practical engineering materials like metals are complex, inhomogeneous collections of crystals or grains. These grains have different behaviors dependent on orientation and surroundings. While for practical applications (e.g. design of automotive parts) a materials response under stress is often estimated ignoring these effects, many behavioural aspects cannot be understood without considering the inherently inhomogeneous local characteristics. My research looks at the influence of local inhomogeneity and resulting internal stress on materials deformation and the processes occurring under stress and temperature fluctuations. The research has an impact on understanding deformation and on the development of practical engineering techniques and component design.
