【摘要】 本文建立了复合材料疲劳寿命曲线的“有效缺陷模型”，阐明了模型中两个参数的物理意义。通过实验验证，说明该模型可以较好地预测复合材料的疲劳寿命。利用该模型，仅需较少的试验即可绘制出新材料的Ｓ－ Ｎ 曲线。更多还原

【Abstract】 The effective flaw model is developed to describe the S-N curves of composite materials.The two fitted parameters in the model have certain physical meaning.It can be seen that the model can predict the fatigue life of composites well from the experimets. Using the model,only a few tests are requried to describe the sketch of the S-N curve of a new material under the fatigue loading.更多还原
