Abstract

Constant amplitude fatigue loading spectra stand for only a small percentage of the real loading of a structure, although they can be used to investigate the fatigue and fracture behavior of structural elements. The fatigue and fracture behavior of adhesively-bonded structural joints under different constant amplitude loading patterns has been experimentally investigated and the results are presented in this chapter. Double-lap joints composed of pultruded glass-fiber-reinforced polymer-matrix laminates bonded by an epoxy adhesive were examined. The dominant failure modes are described and the stiffness degradation trends under tensile or compressive fatigue loads are presented. The results show a significant effect of the loading pattern on the lifetime and fracture behavior of the joints examined.

Composite material

A composite material (also called a composition material or shortened to composite, which is the common name) is a material which is produced from two or more constituent materials. These constituent materials have notably dissimilar chemical or physical properties and are merged to create a material with properties unlike the individual elements. Within the finished structure, the individual elements remain separate and distinct, distinguishing composites from mixtures and solid solutions.

Engineered wood

Engineered wood, also called mass timber, composite wood, man-made wood, or manufactured board, includes a range of derivative wood products which are manufactured by binding or fixing the strands, particles, fibres, or veneers or boards of wood, together with adhesives, or other methods of fixation to form composite material. The panels vary in size but can range upwards of and in the case of cross-laminated timber (CLT) can be of any thickness from a few inches to or more.

Fiberglass

Fiberglass (American English) or fibreglass (Commonwealth English) is a common type of fiber-reinforced plastic using glass fiber. The fibers may be randomly arranged, flattened into a sheet called a chopped strand mat, or woven into glass cloth. The plastic matrix may be a thermoset polymer matrix—most often based on thermosetting polymers such as epoxy, polyester resin, or vinyl ester resin—or a thermoplastic.
