In response to a previous investigation on the influence of specimen pre-shear and wrinkling on the accuracy of uniaxial bias extension test results (Alsayednoor et al. [1]), numerical and experimental investigations have been conducted, aimed at evaluating the use of transparent anti-wrinkle plates to mitigate errors due to wrinkling of engineering fabrics. Predictions of the numerical investigation suggest that the anti-wrinkle plates significantly improve the accuracy of kinematic measurements while introducing only a very minor stiffening effect on the axial force versus shear angle data. Results from subsequent experiments on two different engineering fabrics confirmed the numerical predictions; the accuracy and repeatability of test data was significantly improved and the maximum shear angle and axial force data measurable in the tests was significantly increased. The investigation suggests a useful role for anti-wrinkle plates in characterising the formability of engineering fabrics.

为了响应先前关于试样预剪切和起皱对单轴偏压延伸测试结果准确性的影响的研究（Alsayednoor等人[1]），进行了数值和实验研究，旨在评估透明材料的使用。防皱板，以减轻由于工程织物起皱而引起的错误。数值研究的预测表明，抗皱板可显着提高运动学测量的准确性，同时对轴向力与剪切角数据的影响仅很小。随后在两种不同的工程织物上进行的实验结果证实了数值预测。测试数据的准确性和可重复性得到显着提高，并且在测试中可测量的最大剪切角和轴向力数据得到了显着提高。研究表明，抗皱板在表征工程织物的可成形性方面起着有用的作用。
