At room temperature, the brittle fracture is dominated by the shear band's formation and expansion. A large amount of radiating vein-like morphologies and the liquid droplets can be observed on the fracture surface. The calculation found that the adiabatic heating makes the temperature of the fracture surface layer higher than the liquidus temperature. At the glass transition temperature, the fracture mode is still brittle fracture. Dimples, vein-like morphologies and liquid droplets occupy the fracture surface. The adiabatic heating induces the temperature of fracture surface layer to be higher than the liquidus temperature too. With the temperature increasing or the strain rate decreasing, the necking fracture appears. The fracture surface displays the vein-like morphologies without the liquid droplets. The affection of the adiabatic heating is so weak that the temperature of the fracture surface layer can not increase obviously.
