Journal ArticleDOI
Delta T source location for acoustic emission
TL;DR: In this article, an artificial source is used to record differences in times of arrival information from a number of locations, to improve source location in complex geometric structures, and a 5-step description of the process is provided.
Journal ArticleDOI
An anisotropic, hyperelastic model for skin: experimental measurements, finite element modelling and identification of parameters for human and murine skin.
TL;DR: A finite element model was developed using the transversely isotropic, hyperelastic constitutive model of Weiss et al. (1996) and was able to represent the nonlinear, anisotropic behaviour of the skin well and permitted quantification of the mechanical differences between human and murine skin.
Journal ArticleDOI
Composite technology in load-bearing orthopaedic implants
TL;DR: The range of possible composite biomaterials is reviewed, together with the possible methods of fabrication and the limitations that these place on the design of composite components.
Journal ArticleDOI
Laser powder bed fusion of Hastelloy X: Effects of hot isostatic pressing and the hot cracking mechanism
Quanquan Han,Raya Mertens,Maria L. Montero-Sistiaga,Maria L. Montero-Sistiaga,Shoufeng Yang,Rossitza Setchi,Kim Vanmeensel,Brecht Van Hooreweder,Samuel Lewin Evans,Haiyang Fan +9 more
TL;DR: In this paper, the effect of post-treatment hot isostatic processing (HIP) on the microstructure and mechanical properties of LPBF-fabricated Hastelloy X, with an emphasis on fatigue performance, was investigated.
Journal ArticleDOI
Measuring the mechanical properties of human skin in vivo using digital image correlation and finite element modelling
TL;DR: In this article, a finite element model was used to optimize the material properties to obtain the best match with the model data, and the results were obtained using a Hager-Zhang non-linear conjugate gradient solver.
