Computational comparison of aortic root stresses in presence of stentless and stented aortic valve bio-prostheses

Alfio Quarteroni, Christian Vergara, Elena Faggiano

We provide a computational comparison of the performance of stentless and stented aortic prostheses, in terms of aortic root displacements and internal stresses. To this aim, we consider three real patients; for each of them, we draw the two prostheses con ...

Dynamic behavior of rock during its post failure stage in SHPB tests

Yang Zou, Yang Zhao, Xin Cai

In order to investigate the micro-process and inner mechanism of rock failure under impact loading, the laboratory tests were carried out on an improved split Hopkinson pressure bar (SHPB) system with synchronized measurement devices including a high-speed ...

Structural and functional alterations in the prefrontal cortex after post-weaning social isolation: relationship with species-typical and deviant aggression

Maria del Carmen Sandi Perez, Samuel Bendahan

Although the inhibitory control of aggression by the prefrontal cortex (PFC) is the cornerstone of current theories of aggression control, a number of human and laboratory studies showed that the execution of aggression increases PFC activity; moreover, en ...

Fatigue performance of a cold-curing structural epoxy adhesive subjected to moist environments

Thomas Keller, Anastasios Vassilopoulos, Maria Savvilotidou

This paper presents the results of an experimental program designed to study the effects of aging and a wet environment on the fatigue behavior of epoxy resins used in bridge applications. Specimens were manufactured, cured, and treated, before the experim ...

Probabilistic S-N curves for constant and variable amplitude

Alain Nussbaumer, Cláudio Alexandre Pereira Baptista, António José Luís dos Reis

Welded details in steel bridges are subjected to fatigue lives up to 200.10(6) cycles due to traffic loads. While the majority of these stress ranges are below the Constant Amplitude Fatigue Limit (CAFL), some few high stress cycles can trigger the start o ...

Tailoring residual stress profile of Selective Laser Melted parts byLaser Shock Peening

Roland Logé, Eric Boillat, Nikola Kalentics

The paper describes a new approach in controlling and tailoring residual stress profile of parts made bySelective Laser Melting (SLM). SLM parts are well known for the high tensile stresses in the as – built statein the surface or subsurface region. These ...

Stable room-temperature micron-scale crack growth in single-crystalline silicon

Andreas Mortensen, Goran Zagar, Martin Guillermo Mueller

Room-temperature fracture along the (111) plane of silicon is probed at the micron-scale using chevron notched cantilever beams that enable stable crack growth before unstable fracture in successful tests. The main experimental observation is that a growin ...

Stress intensity factors for axial semi-elliptical surface cracks and embedded elliptical cracks at longitudinal butt welded joints of steel-lined pressure tunnels and shafts considering weld shape

Anton Schleiss, Pedro Filipe De Almeida Manso, Alexandre Jean Pachoud

When for steel liners of pressure tunnels and shafts high-strength steels are used, welded joints are subject to the risk of hydrogen induced cold-cracking in the base material. Longitudinal butt welded joints are critical regions as they are loaded transv ...
