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.

像金属这样的实际工程材料是复杂的、不均匀的晶体或颗粒集合。这些颗粒具有取决于取向和环境的不同行为。虽然在实际应用中（例如汽车零件的设计），材料在应力下的响应往往是估计忽略这些影响，许多行为方面不能理解不考虑固有的不均匀的局部特性。我的研究着眼于局部不均匀性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。这项研究对理解变形和实际工程技术和部件设计的发展产生了影响。
