Abstract Fiber metal laminates (FML) are hybrid materials consisting of and composite layers. They have great mechanical fatigue properties. However, interface between layers can be critical for their final In this paper, process determination some fracture parameters in unusual FML material is described. Experimental tests following ASTM norm were conducted using Double Cantilever Beam (DCB). ...

Delaminations in composite laminates resulting from impact events may be accompanied by minimal indication of damage at the surface. As such, inspection techniques are required to ensure defects are within allowable limits. Conventional ultrasonic scanning techniques have been shown to effectively characterize the size and depth of delaminations but require physical contact with the structure. ...

Problem statement: This study showed the results of an experimental investigation on the strengthening of corrosion damaged reinforced concrete beams with unidirectional cloth glass fiber reinforced polymer (UDCGFRP) laminates. Approach: All the beam specimens 150×250×3000 mm were cast and tested for the present investigation. One beam specimen was neither corroded nor strengthened to serve as ...

T he use of fiber reinforced polymers (FRP) for reinforcement of aging and deteriorating concrete members has emerged as a viable and costeffective alternative to traditional repair and strengthening techniques. Their use enables upgrading of deficient structures to meet today’s design standards (Crasto et al., 1996; Myers et al., 2000). The loadcarrying ability of structures such as beams and ...

In the present paper the damage of fiber-reinforced polymeric matrix laminates is considered with the aim to examine their mechanical properties. The damage mode in the form of intralaminar cracks (“primary matrix cracking”) is described in terms of second order, symmetrical damage tensor by Vakulenko and Kachanov. It allows for considering the orientation of the defects, which is determined by...
