Size effect in fracture of unidirectional composite plates

1/1/1999· Fracture of notched, unidirectionally reinforced composite plates with well-bonded ductile matrices is typically preceded by the formation of long, discrete plastic shear zones aligned in the fiber direction. Onset of fracture is associated with a critical tension stress in ...

Effect of prestressed CFRP patches on crack growth of

Prestressing the CFRP patches before attaching them to the notched steel plates has a considerable effect on their fatigue life. Comparing D2L50 with D2L represents an increase in the cracked life of about 10 times and 6.5 times under load (I) and load (II) respectively, which shows the difference between a prestressed specimen versus a non-prestressed specimen.

High-Velocity Impact Behaviour of Prestressed

An experimental and numerical analysis of the response of laminated composite plates under high-velocity impact loads of soft body gelatine projectiles (artificial birds) is presented. The plates are exposed to tensile and compressive preloads before impact in order to cover realistic loading conditions of representative aeronautic structures under foreign object impact. The modelling ...
