We have examined the yielding and fracture behavior of Zr57.4Cu16.4Ni8.2Ta8Al10 metallic-glass-matrix composites with a small volume fraction (similar to 4 pct) of ductile crystalline particles under quasi-static uniaxial tension and compression and dynami ...
Bone is a complex and very important multi-constituent bio-composite. In this work, we focus on the arrangement of bone constituents from the nanoscopic to the microscopic scale, and investigate the influence of their arrangements on the fracture mechanism ...
This work addresses nonlinear finite element analysis of laminated structures with weak interfaces. Considered first are shallow laminated beams subject to arbitrary large displacements, small layer strains and moderate interface slippage. Under these requ ...
We have used in situ X-ray scattering and finite element modeling (FEM) to examine the micromechanics of deformation of in situ formed metallic-glass-matrix composites consisting of Ta-rich particles dispersed in an amorphous matrix. The strain measurement ...
The frequent use of soils and earth materials for hydraulic capping and for geo-environmental waste containment motivated our interest in detailed modelling of changes in size and shape of macro-pores to establish links between soil mechanical behaviour an ...
Bone is a complex porous composite structure with specific characteristics such as viscoelasticity and anisotropy, both in morphology and mechanical properties. Bone defects are regularly filled with artificial tissue grafts, which should ideally have prop ...
A systematic approach to understanding the role of microstructure on the mechanical response of complex multiphase materials is presented based on the "microstructure reconstruction" method of Yeong and Torquato. Low-order statistical correlation functions ...
BACKGROUND: Although shoulder arthroplasty is an accepted treatment for osteoarthritis, loosening of the glenoid component, which mainly occurs at the bone-cement interface, remains a major concern. Presently, the mechanical effect of the cement mantel thi ...
The mechanical properties of healthy and diseased bone tissue are extensively studied in mechanical tests. Most of this research is motivated by the immense costs of health care and social impacts due to osteoporosis in post-menopausal women and the aged. ...
This paper presents a finite element calculation of frictionless, non-adhesive, contact between a rigid plane and an clasto-plastic solid with a self-affine fractal surface. The calculations are conducted within an explicit dynamic Lagrangian framework. Th ...
