On Generalized Varga Materials
研究了广义Varga材料能量泛函极小元的存在性与正则性，发现除原点空化外，体内还出现球形断裂的新现象。
Abstract We study the existence and regularity of minimizers of an energy functional which in the physical 3D dimension corresponds to the so–called generalized Varga materials and includes an additional term accounting for surface tension. Due to the linear growth of the strain energy, we relax the problem in a suitable class of extended graphs of radially symmetric functions of bounded variations. Besides cavitation at the origin, a new phenomenon due to the occurrence of a spherical fracture inside the body is observed.
