The development of a mechanistic understanding of the increase in fracture risk in human bone with age is essential to public health. This represents a challenge for fracture mechanics as bone has a complex, hierarchical structure with characteristic

The adverse effects of stress shielding from the use of high-modulus metallic alloy bio-implant materials has led to increased research into developing polymer-ceramic composite materials that match the elastic modulus of human bone. Of particular in

Data for fracture in human humeral cortical bone are re-analyzed to assess the validity for this material of linear-elastic fracture mechanics (LEFM), which is the standard method of analyzing toughness and one basis for analyzing clinical data relat

High-cycle fatigue (HCF), involving the premature initiation and/or rapid propagation of cracks to failure due to high-frequency cyclic loading, remains a principal cause of failures in gas-turbine propulsion systems. In this work, we explore the fea
