ジャーナル フリーThe purpose of the present study is to obtain the fatigue limit diagram (FLD) and S-N diagram (SND) for transverse cracking in fiber reinforced plastic laminates under fatigue loading on the basis of the probabilistic slow crack growth (SCG) model. First, the deterministic and probabilistic FLD and SND were discussed for formulation. Next, the transverse crack density ρ was measured against number of cycles for various stress ratios R at a constant maximum stress to experimentally determine the parameters associated with the probabilistic SCG model. Finally, the FLD and SND were derived from the relationship among, ρ, R and fatigue life using the above parameters.抄録全体を表示PDF形式でダウンロード (1237K) -

ジャーナル フリーIn order to investigate effects of lamination thickness on the damage progress due to out-of-plane loading in FW-CFRP composite pipes, impact and quasi-static indentation tests were conducted. Absorbed energy decreased with number of plies and saturated. Damages, such as indentations, splittings and fiber breakages, occurred around a loading point. Propagation of fiber breakages and splittings is larger in specimen after quasi-static indentation tests than those of impact. These damages were localized with number of plies. Residual deflections of aluminum liners were also suppressed with number of plies. Residual burst strength ratio increased more than 70% for the absorbed energy ratio of less than 10 J/m.抄録全体を表示PDF形式でダウンロード (3360K)
