摘要
用侧向透裂纹试样测定了一种新型高阻尼铝合金层压板及其组成层之一的防锈铝（ＬＦ４）合金板的疲劳裂纹扩展速率，得出了相应的Ｐａｒｉｓ表达式。与经受相同加工、热处理的防锈铝板相比，层压析具有较高的疲劳裂纹扩展速率，层压板中强度好高的组成层是使层压板具有较小疲劳裂纹扩展速率的主要因素。
The fatigue crack growth rate of a high damping aluminium-alloy laminate and a Al-Mgallov i.e. LF4 has been measured.LF4 is one of the component layers of laminate. The Parisexpression of the laminate and LF4 has been obtained from the experimental results.
