传统意义上车辆的超载是指车辆当前负荷高于该车型的额定载荷。
Traditionally, the vehicle overload is defined as the load that exceeds its rated load.
要准确预测结构在变幅载荷谱下的疲劳裂纹扩展寿命，必须研究超载对裂纹扩展的影响。
Therefore, it is necessary to evaluate the influence of overloads on crack growth rates for the fatigue life prediction of structures subject to variable amplitude loadings.
试验研究了裂纹扩展过程中超载载荷迟滞效应。
The hysteresis that was induced by overload was investigated experimentally.
