Fatigue and Fracture of Anisotropic Materials

Dear Colleagues,

Anisotropic materials, which exhibit varying mechanical properties in different directions, are omnipresent in our modern industry. From traditional rolled alloys to single crystals used at high temperatures, to increasingly popular additive manufacturing materials, anisotropy plays a fundamental role in shaping material performance and structural integrity. Consequently, understanding the mechanical behaviours of anisotropic materials is a paramount concern with broad implications across multiple disciplines.

The mechanical response of anisotropic materials is closely related to their microstructure, loading conditions, and service environment. Over the past few decades, there has been extensive reporting on the anisotropic mechanics and deformation behaviours exhibited by crystal materials. However, most of the current research primarily concentrates on common mechanical properties and deformation. There is a lack of research on the mechanical behaviour of anisotropic materials in complex mechanical environments, especially in clarifying fracture, fatigue crack propagation, fatigue damage, and failure mechanisms through advanced characterization methods and numerical analysis models.

It is with great pleasure and enthusiasm that we introduce this Special Issue dedicated to the exploration of "Fatigue and Fracture of Anisotropic Materials". As the guest editors of this issue, we would like to extend our warmest welcome to all contributors and readers who share our passion for advancing our understanding of the complex mechanical behaviours of anisotropic materials.

This issue brings together a collection of research articles and case studies that delve into the anisotropic material fatigue and fracture behaviour. From experimental investigations unravelling the fatigue life of anisotropic materials to numerical simulations elucidating crack propagation in anisotropic solids, this Special Issue showcases the diversity and richness of research within this field. Key areas of interest covered in this issue include but are not limited to:

(a) Fatigue behaviour and life prediction of anisotropic materials;

(b) Fracture mechanics and crack propagation in anisotropic solids;

(c) Experimental techniques and testing methodologies for anisotropic materials;

(d) Damage mechanics and failure criteria for anisotropic structures;

(e) Numerical modelling and simulation of anisotropic material.

I look forward to receiving your contributions.
