单晶硅是电脑芯片、新能源、光纤通信等重要材料，属于脆性材料，在使用中易受接触载荷作用而引起不同程度的表面损伤，导致裂纹产生，影响使用寿命，这种接触损伤状态与材料一系列力学行为、材料的表面原始状态、加载形式以及外界环境等因素密切相关。近几年来，压痕断裂...
Monocrystalline silicon is an important material such as a computer chip, a new energy source and an optical fiber communication. It is a brittle material, and is susceptible to contact load and causes different degrees of surface damage during use, resulting in cracks and affecting the service life. The contact damage state and A series of mechanical behavior of the material, the original surface state of the material, the loading form and the external environment and other factors are closely related. In recent years, indentation fracture ...
