本文研究正交复合材料平面板剪切模量G_(12)的五种较常用的测定方案。从同一板材裁取的试件,在线弹性范围内依次用这些方案进行了试验。试验表明其结果是比较一致的。这一结果给我们提供了根据各自条件采取合适的方案开展G_(12)测定工作的依据。 另外,文中还用了较多的篇幅来比较、讨论了各种方案的优缺点、难易程度、试件耗费以及各个方法的使用特点。
In this paper, five commonly used methods for determining the shear modulus of planar plates of orthogonal composites (G 12) are studied. Specimens cut from the same plate were tested with these solutions in the on-line flexibility. Experiments show that the results are more consistent. This result gives us the basis for carrying out the G_ (12) determination according to the respective conditions. In addition, the article also uses more space to compare and discuss the advantages and disadvantages of various programs, ease, specimen cost and the use of each method features.
