Study of crack healing effect in dimethyl phthalate crystals by mechanical spectroscopy
邻苯二甲酸二甲酯晶体中裂纹愈合效应的力学谱研究

The recently developed method to detect the stress-cracking and crack healing of glasses in real-time (called the RMS-CH in short,Wu et al.,Appl. Phys. Lett. 92,011918-1(2008)) is applied to the detections of crystals . The experimental results of dimethyl phthalate crystal indicate that,under the condition of constant heating rate:1) the crack-healing rate shows a sharp peak as a function of temperature,the peak temperature can be taken as the chara cteristic temperature T~c_ch of the crack-healing ,and T~...
