Fatigue behavior of laminated composites with a circular hole under in-plane multiaxial loading

Experimental methods and standards for fatigue of fiber-reinforced composites

“…There is very little information about multiaxial fatigue testing (Chen & Matthews, 1993;DeTeresa, Freeman, & Groves, 1998;Huang et al, 2010;Lee & Hwang, 2001;Makris, Ramault, Van Hemelrijck, Lamkanfi, & Van Paepegem, 2008;Jweeg, Hasan, & Kahtan, 2013;Satapathy, Vinayak, Jayaprakash, & Naik, 2013;, 2003. It is interesting to note two different approaches demonstrated in (Chen & Matthews, 1993;Jweeg et al, 2013): the use of a self-made fixture and a special testing machine for biaxial tension.…”

50th Anniversary Article: Multiaxial Fatigue Testing of Composites: From the Pioneers to Future Directions

“…In the case instead of a unidirectional stacking sequence, the direct effect of transverse stress σ 2 over the normal stress σ 1 can be investigated, and this can be of help for microscopic damage investigation purposes. However, in spite of the comprehensive and careful investigations on fabric reinforced laminates presented in [62] and few other researches [63][64][65][66][67], the results reported so far show how difficult is in general to obtain failure in the calibrated section of the specimens under fatigue. Moreover, stress concentrations due to the milling required to produce the calibrated section are frequently the undesirable sites of damage initiation.…”

Estimation of Notched Composite Plates Fatigue Life Using Residual Strength Model Calibrated by Step-Wise Tests

“…The phenomenon of stress concentration in thin plates with a cut-out and modelling of fatigue damage under unidirectional loading using different fatigue models was recently discussed in many papers [6,7,8,9,10,11,12]. Some experimental investigations of fatigue behaviour of notched composite plates under multiaxial loading condition were also performed [13,14,15,16,17,18].…”
