摘　　要：基于数字图像相关方法(DIC),搭建了一套基于该方法的纯弯曲梁教学实验平台,并同时采用电测法和DIC法测试了梁的弯曲应变。结果表明,两种方法测试得到的应变值基本一致,表明DIC方法具有较高的测试精度,可以应用于工程力学实验的教学。该平台可以开拓学生的视野,并激发学生的实践能力,为培养新世纪的复合型实用人才提供平台基础。Built a teaching experiment platform for pure bending test based on digital image correlation method(DIC),and tested the bending strain of the beam by both electric measurement method and DIC method.The results show that the strain values obtained by this two methods are basically the same,indicating that DIC method provides a higher measured accuracy,which can be applied to the course of engineering mechanics experiment.This platform can be used for broadening horizon and stimulate practical ability of students,which provide a platform basis for cultivating practical and inter-disciplinary talents.
