宽带试样变形对物理性能影响

Effect of Deformation in Broad-band Specimen on Physical Properties

物理检测中常发现试样有不同程度变形,主要有弯曲与扭转变形,严重影响试样物理性能的准确性。文章对宽带试样变形的产生原因及试样变形对物理性能的影响进行了分析。

During physical testing, there often found the deformation in samples in some degrees, most of which is bending or torsion deformation, seriously affecting the tested accuracy. In this paper, the causes of deformation in samples are analyzed.
