This work has evaluated a graphite of the type used in rocket nozzles by the Iosipescu test and the resulted stress, ~11 MPa, was found to be equal to the tensile strength. Thus, the tensile strength can be evaluated just by a single and simple experiment, thus avoiding complicated ...

Experimental Determination of the In Situ Transverse Lamina Strength in Graphite/Epoxy Laminates The uniaxial tensile load at which transverse cracking initiated in the 90 deg. laminae of (0 2/90n)s, (卤30/90n) s and (卤60/90n)s, n =1,2,4,8, T300/934 composite laminates was ...
A simple relation is used for the characteristic length to improve the accuracy while evaluating the notched tensile strength of laminates through the Whitney-Nuismer fracture models. The Whitney-Nuismer model postulates the final fracture of a notched composite laminate. The two stress fracture criter...
It is well understood that, in the case of a structure with a fully dense material, the presence of cracks, notches, and holes results in a stress ... Kidane,Addis - 《Isrn Materials Science》 被引量: 17发表: 2013年 Assessement of tensile strength of graphites by the Iosipescu coupon...

通过在压缩载荷下在边缘加载圆盘状试样,产生的横向于加载轴的拉伸应力提供了石墨抗拉强度特性的指示.为了获得一致且有意义的劈裂抗拉强度值,至关重要的是,断裂发生在圆盘的中心,而不是沿着边缘.该标准试验有助于确保圆盘试样由于垂直于加载轴的拉伸应力而沿加载直径发生径向断裂,并且断裂始于圆盘中心. 4.2 使用径向...
Impact resistance and interlaminar fracture toughness of through-the-thickness reinforced graphite/epoxy strengths 20-25 percent lower than the strengths of unstitched laminates, the tension strength of stitched laminates is reduced with increasing number of stitches, and the compression strength increases...
