The influence of cementation on liquefaction resistance of sands
… soils, and are not capable of modeling the effects of multiaxial loading. In this investigation, there were two major objectives. The first involved the development and fabrication of a new three~dimensional shear device with the capability of applying load to cemented sands with a minimum …

Interacting stress concentration factors and their effect on fatigue of metallic aerostructures
… or some other similar detail. The interaction of stress concentration effects between a hole and step are not well understood and the resulting impact on fatigue performance is difficult to predict. There exists a need for fatigue data that can be used to determine the analysis methods for …

Constraint and Ductile Tearing Effects on the Cleavage Fracture of Ferritic Steel
… in terms of KJc (or Jc) values with the Weibull stress model, i.e ., the ""local approach"" for fracture at the micro-scale. The E1921 procedures assume that uniform, small-scale yielding (SSY) conditions exist at fracture along the full crack-front. Plasticity induced constraint loss …

Multi-axial fracture behaviour of notched carbon-fibre/epoxy laminates
… light, stiff and strong. They commonly contain stress raisers in the form of holes and notches (for mechanical joining methods, routing of pipes and cables etc.) and are also often subjected to complex combined multi-axial stress conditions during service. Yet their notched multi-axial fracture …

Experimental and Numerical Investigation of the Micromechanical Behavior of Selective Laser Melted Ti-6Al-4V Cellular Lattices for Biomedical Applications
… to the their as-designed geometry and its effects on the elastic modulus and the fatigue resistance. In this regard, the purpose is to develop quantitative relationships between the as-designed and the as-built geometry in order to obtain design tools to predict the final morphology of the …
