Composite materials are widely used to build structural components, thanks their mechanical properties. Those generally considered 'engineering materials', since they tailored meet specific requirements. Due use for it is important know behaviour, especially under cyclic loads. At present, there a common interest, among researchers, study the behaviour of composites, by means both traditional and innovative techniques, with final purpose making previsions regarding service life. In fact, due...
ABSTRACT Many biological materials are generally considered composites, made of relatively weak constituents and with a hierarchical arrangement, resulting in outstanding mechanical properties, difficult to be reached man‐made materials. An example is human bone, whose structure strongly affects its performance, toughness particular, by activating different toughening mechanisms occurring at length scales. At microscale, the principal mechanism bone crack deflection. Here, we study focus on...
The influence of hydrogen on the mechanical behavior a quenched and tempered 42CrMo4 steel has been evaluated by means high internal pressure fracture tests carried out precharged notched cylindrical specimens. specimens were for 3 h time with 1.2 mA/cm2 in two different aqueous media: 1 M H2SO4 added 0.25 g/l As2O3 3.5% NaCl solution. Hydraulic performed at ramps pressure: 7000, 220, 80, 60 30 MPa/h, respectively. Hydrogen damage was more marked when acid medium (1 + As2O3) employed. In...
Dual Energy X-Ray Absorptiometry (DXA) is currently the most widely adopted non-invasive clinical technique to assess bone mineral density and content in human research represents primary tool for diagnosis of osteoporosis. DXA measures areal density, BMD, which does not account three-dimensional structure vertebrae distribution mass. The result that longitudinal can only predict about 70% vertebral fractures. This study proposes a complementary tool, based on Finite Element (FE) models,...
Thiamine is a crucial cofactor involved in the maintenance of carbohydrate metabolism and participates multiple cellular metabolic processes. Although thiamine can be obtained from various food sources, some common groups are deficient thiamine, it denatured by high temperature pH. Additionally, different drugs alter metabolism. In addition, half-life body between 1 3 weeks. All these factors could provide an explanation for relatively short period needed to develop deficiency observe...
The fracture behavior of human bone is an interesting field research for medical scientists, which are interested in predicting the risk, but also engineers, mimicking structure design new materials. To understand this phenomenon and to be able make predictions, many numerical techniques currently adopted, with goal reaching different length scales. In paper we present a study microstructure bone, via cohesive-based X-FEM approach. A single osteon model developed investigate mechanisms crack...
Purpose Composite materials are increasingly used in the structural and mechanical fields, thanks to their high strength‐to‐weight ratios possibility of tailoring them meet specific requirements. This study is focused on damage a glass fiber reinforced composite under different loading conditions. The aim find, by coupling tests with thermal analyses, parameter, able define initiation studied material. Design/methodology/approach object this work glass‐fiber plastic (GFRP) laminate. To...
The use of additive manufacturing (AM) technique is recently increased due to its ability in producing complex-shaped components. AlSi10Mg alloy largely employed for AM and, particular, selective laser melting (SLM). Hence, the interest on this growing, together with studies control mechanical performances, which can be by microstructure modification. With focus, low temperature heat treatments enhance behavior have been proposed recent literature. present work focuses two post-additive...
Abstract The comprehension of trabecular bone damage processes could be a crucial hint for understanding how starts and propagates. Currently, different approaches to identification followed. Clinical start from dual X-ray absorptiometry (DXA) technique that can evaluate mineral density (BMD), an indirect indicator fracture risk. DXA is, in fact, two-dimensional technology, BMD alone is not able predict the effective risk fractures. First attempts overcoming this issue have been performed...
