BACKGROUND We examined the association between quality of care and 30 day mortality in a nationwide cohort of patients hospitalized with hip fracture. METHODS We used data from The Danish National Indicator Project, a quality improvement initiative with participation of more than 90% of Danish hospital departments caring for patients with hip fracture between August 16, 2005 and August 15, 20...

Developments in computer-aided engineering and the rapid growth of computational power have made simulation-driven process and product development efficient and useful since it enables detailed evaluation of product designs and their manufacturing processes. In the context of a sheet metal component, it is vital to predict possible failure both during its forming process and its subsequent usag...

Many delamination failure criteria based on fracture toughness have been suggested over the past few decades, but most only covered the region containing mode I and mode II components of loading because that is where toughness data existed. With new analysis tools, more 3D analyses are being conducted that capture a mode III component of loading. This has increased the need for a fracture crite...

Ductile fracture through growth and coalescence of intergranular cavities is a failure mode observed experimentally in many metallic alloys used industrial applications. Simulation this process polycrystalline aggregates requires modeling the plastic yielding porous boundaries. However, classical yield criteria for materials such as Gurson–Tvergaard–Needleman model its current extensions cannot...
