Abstract

During three-point-bending fatigue tests with predominant shearing on a unidirectional glass/epoxy composite, caulking is observed under the rollers on all loaded specimens. If fatigue tests are controlled in displacement, caulking induces a change in loading conditions during cycling, and the damage in the material is reduced.

在V/E-UD中以剪切为主的三点弯曲疲劳疲劳的影响
在单向玻璃/环氧复合材料的三点弯曲主要剪切疲劳试验中,在所有加载试样的滚轮下都观察到填缝现象。如果疲劳试验控制在位移范围内,则填缝在循环过程中引起加载条件的变化,从而减少材料的损伤。
