The bonding strength calculating formulas are presented. Which were referred to the tensilecharacteristic of concrete, and shows good agreement with the test results.
给出了与混凝土本身抗拉性能相关的、与试验结果符合良好的粘结强度计算公式。
2
Characteristic of this design is high reliability, small volume, big tensile force end so on.
此设计的特点是：可靠性高、体积小、拉力大等。
3
Meanwhile, strain hardening capacity of FSW joint in cooling water also enhances, and the tensile fracture presents the characteristic of microporous polymeric fracture.
