Abstract The conception of aircraft morphing wings thrives in aeronautics since the appearance of shape memory alloys (SMAs). An aircraft morphing wing device, manipulated by an SMA actuator, inherits the intrinsic nonlinear hysteresis from the SMA actuator, ending up with control disadvantages. Conventionally, systems with SMA actuators are constrained to bi-stable states to bypass the hysteresis region. Rather than retreating a morphing wing device to bi-stable states, this paper is dedicated ...

Abstract In the previous two parts of this series of papers, the fabric structures of three-dimensional braided composites were simulated and the fibre volume fraction was derived [Z.X. Tang, R. Postle, Compos. Struct. 49 (2000) 451]. The models of tensile and shear moduli for three-dimensional braided composites were established by computer simulation and mathematical modelling. The results predicted from the modulus models were supported by the experimental data [Z.X. Tang, R. Postle, Compos. ...

Abstract In the first part of this series of paper [Z.X. Zang, R. Postle, Mechanics of three-dimensional braided structures for composite materials – Part I: fabric structure and fibre volume fraction, Comp. Struct. 49 (2000) 451–459], it was demonstrated that the braiding angles and fibre volume fraction can be represented as functions of the normalized pitch length introduced as a key parameter of three-dimensional braided reinforced composite materials. In the present paper, the models for th...

This paper is the first part of a series on the mechanics of three-dimensional braided structures for composite materials which include fabric structure and fibre volume fraction models, prediction of mechanical properties, finite element analysis and simulation of deformations. In the present paper, the normalized pitch length is introduced as a key parameter of three-dimensional braided structures. It is demonstrated that the braiding angles and fibre volume fractions can be represented as fun...
