A simple analytical model is developed for the evaluation of the bending stress caused by the misalignment of the ends of a glass fiber specimen soldered into a ferrule and subjected to tension during pull testing. It is shown that this stress can be reduced by use of sufficiently long specimens. It is also shown how the uncertainty in the prediction of the misalignment of the ends can be considered when one is establishing the appropriate specimen length.
建立了一个简单的分析模型,用于评估在拉伸试验中,焊接在插芯中的玻璃纤维试样两端未对准所产生的弯曲应力。结果表明,使用足够长的试样可以降低这种应力。还展示了在确定合适的试样长度时,如何考虑两端未对准预测中的不确定性。
