Abstract— The paper discusses the results of fatigue crack growth rate tests conducted in presence residual stresses. Three different stress distributions, obtained by laser welds, were employed order to characterize propagation behaviour under conditions, producing either an increase or a reduction intensity factor due external loads. Test are analysed means non‐linear numerical model (based on weight function method) and knowledge properties base material, free from analysis discussed with...
A flow above a cavity leads to an unsteady separated flow. This configuration exhibits intense aeroacoustic coupling, where very aerodynamic noise can be emitted. Moreover, majority of tangential has oscillatory character, resulting from strong coupling between the acoustic and dynamics. In present work, we are interested in characterizing dynamics frequency distribution First, analyzed is established, which followed by study nonlinear interaction. An open loop control using synthetic jet...
Abstract The paper deals with the development of a numerical method for determining Weight Functions in two‐dimensional problems. After short review some recent techniques an original approach is presented. based on Finite Element calculations coarse meshes and knowledge values Stress Intensity Factor one reference loading condition. validity demonstrated theoretical case its accuracy suitability are discussed to practical applications.
Abstract— An overview is presented of studies conducted at the University Pisa on Weight Function technique as applied to Fatigue Crack Grown analysis. The fundamental theoretical aspects are summarised, discussing some recent methods for determination Function. application non‐linear (contact) problems and evaluation crack tip stress field also discussed. It shown that method allows one efficiently consider many propagation problems, examples which provided.

ABSTRACT The oil pollution prevention program of the U.S. Environmental Protection Agency (EPA) addresses a large regulated community—the owners and operators several hundred thousand nontransportation-related facilities. Regulated facilities generally are thought as refineries, terminals, production field tanks, fuel dealers, or gasoline service stations. Some studies nationwide petroleum storage capacity do not even consider tanks owned by consumers, while others recognize that end users...
In this paper we present a mixed thermofluidodynamical and mechanical approach to the life analysis of thermally-loaded components, apply it combustor liner. When studying class problems, are mostly concerned with a) material parameter identification b) load history definition. While testing may alleviate need for point a), must put lot care in b), since distribution temperature (i.e., thermal gradient) inside components their very difficult measure accurately. To face these kind problems...
Si-alloyed pyrolitic carbon (PyC) is currently employed in many biomedical devices, due to its fairly good biological compatibility and non biodegradeability. For prosthetic heart valve applications, required operate safely for years, the resistance abrasive wear one of limiting factors which must be accurately evaluated. The present study reports on testing Ti/PyC PyC/PyC sliding couples. both couples it was found that behaviour can shifted from a low regime, characterised by very small...
<h3>Background</h3> The COVID-19 pandemic has had a major impact on the organisation of health services worldwide. In first wave, many therapeutic options were explored, exposing patients to significant iatrogenic risk. context in which patient management was not well defined by clear recommendations and healthcare professionals under great stress, it still relevant maintain pharmaceutical care or did bring an additional factor disorganisation? <h3>Objective</h3> aim our study compare...
The work is focused on the modeling of creep-fatigue behavior in austenitic stainless steels presence complex loading histories and multiaxial states stress. Two interaction models, namely “Continuous Damage Model” “Damage Rate Approach,” have been applied to predict experimental results time-variable tests. Related application difficulties prediction accuracy are discussed. Life predictions were obtained from computer programs written perform numerical calculations. Material parameters...
