Understanding the fatigue processes in these fibres can suggest ways of eliminating or reducing the probability of unforeseen failures. This book addresses key aspects of fatigue failure in textile fibres.

Part one explains the different types of fatigue failure in textiles such as tensile, torsional and flex fatigue. Biaxial rotation fatigue tests are suitable for synthetic fibres such as nylon with moderate rigidity. These fibres are usually monofilaments of circular cross-section and they can be bent to take fairly severe curvatures required to produce a biaxial rotation fatigue : BS Wong, Xungai Wang.

One of the pioneering works on biaxial fatigue testing of fiber-reinforced plastics by means of cruciform specimens was by Smith and Pascoe (). They tested woven glass fibers–polyester laminates made of two orthogonal layers, oriented at several angles with respect to the loading arms.

biaxial loads to cruciform specimens. In order to do so, a biaxial test device was developed at the Free University of Brussels (VUB) at the Department of Mechanics of Materials and Constructions (MeMC) [9].

This device employs four servo-hydraulic actuators for testing cruciform specimens under static and cyclic loading conditions. Finite elementFile Size: 1MB.

This letter deals with the observed development of (false) twist in fibres subjected to a biaxial rotation-fatigue test. A simple theory in terms of forces and moments is presented from which both the torque and the rate (amount) of twist can be correlated with the viscoelastic properties of the fibreCited by: 2.

Biaxial rotation is a useful method of laboratory fatigue testing of fibres. For thick monofilaments a short length is bent into an arc of a circle and then rotated from both ends.

For fine fibres the bend is concentrated over a pin. In this book about 20 different modes of fibre failure are examined. Case studies have been selected both from the traditional uses of textiles in clothing and in household products, such as sheets, towels and carpets and also from the study of failure in textile structures used in industry and engineering, for example seat belts and ropes.

Fibres are used both for traditional textile applications as well as in advanced technical structures. Understanding the fatigue processes in these fibres can suggest ways of eliminating or reducing the probability of unforeseen failures.

Tensile testing — This type of mechanical testing measures the force required to pull an object — such as a rope, wire or beam — to the point that it breaks. The tensile strength is the.Biaxial testing is an experimental technique which allows the investigation of the mechanical behaviour of materials under complex quasi-static or fatigue loading conditions.These fatigue tests are used to determine the effect of processing, surface condition, stress, and so forth, on the fatigue resistance of plastic material subjected to uniaxial stress for relatively large numbers of cycles.

The results can also be used as a guide for the selection of plastic materials for service under conditions of repeated flexural stress.
