Biography

Gao Yuchen, male, Han nationality, is a native of Changchun, Jilin Province. He graduated from Beijing University in 1960 and received his postgraduate degree from Tsinghua University in 1966.

Gao Yuchen's main research is targeted to the crack tip field, which is the fine visual mechanics of complex material and nonlinear continuous mechanics. With regard to the crack tip field, Gao obtained a series of singular integral of quasistatic extended crack in ideal plastic and power hardened plastic materials. Gao discovered that the singularity of plane strain plastic field is accompanied by shock waves. Gao also discovered that the ideal elastic-plastic mixed-type crack tip field contains an elastic zone. He revealed the extended zone and shrinkage zone of a big deformation elastic crack.

In the field of fine visual mechanics of complex materials, Gao established a bridging model of fiber complex materials and interface fatigue wear models. In the field of nonlinear continuous media mechanics, Gao proposed a constitutive relation of the two kinds of elastic big deformation.

Gao is an academician of the Chinese Academy of Sciences.
