Secondary damage effect on stress redistribution in laminated composites
Intralaminar matrix cracking is recognized as the primary mode of damage appearing in laminates. Local Raman strain measurements in neighboring layers show that the distribution shape in the vicinity of the crack tip is ...
Raman Spectroscopy Assessment of Stiffness Reduction and Residual Strains due to Matrix Cracking in Angle — Ply Laminates
Off — axis ply cracking in composite laminates and especially its effect on composites thermomechanical behaviour has been extensively studied in the case of cross — ply stacking sequence; see Katerelos and Galiotis , ...
Secondary Damage Modes In Laminates Initiated By Intralaminar Cracks
Damage developing within laminated composites is a result of complex combinations of thermomechanical and environmental loads. Intralaminar (transverse) cracking is the first mode of damage appearing. The cracks act as ...
Damage development in composites initiated by matrix cracking
Stress state in the vicinity of transverse crack tip is investigated using an analytical variational model based on principle of minimum complementary energy. Knowing the stress concentration factor’s (SCF) values at the ...
