Abstract

In this study, the notched strengths of three kinds of braided composite plates with a center hole were investigated. Both point stress criterion (PSC) and average stress criterion (ASC) were first applied to find the characteristic length of each braided composite plate with different sizes of the hole. It was found that the characteristic lengths predicted by both criteria are not constants. Based on the concept of three-parameter criterion, the characteristic lengths obtained by both criteria were then proposed to be expressed as functions of hole size as well as width of the plate. The notched strength of braided composite plates was then predicted. Finally, it was shown that both modified PSC and modified ASC gave better predictions of the notched strength than traditional PSC and ASC for all the kinds of braided composite plates.
