Examples
- The micromechanisms of fracture in engineering materials have been studied in this thesis , with particular emphasis on the dislocations behavior in the front of crack tip and the processes of crack nucleation and propagation on nanometer scale . the relation between the microprocesses of fracture and the macromechanical behaviors were investigated , which will be helpful to the strengthening and toughening of engineering materials
本文首先对材料断裂文献进行综述，了解断裂微观机理研究的过去成就、现状和发展，确定本文研究的内容为工程材料断裂的微观机理，侧重裂尖微区位错行为和纳米尺度上微裂纹形核与扩展过程及微观组织的影响，断裂微观过程与宏观力学行为的关系，为工程材料的强韧化提供理论依据。
