1. Fatigue Failure Analysis on Precracked 304 Stainless Steel Components Repaired by Laser with Addition of Nanocomposites
Abstract The service life of components can be extended by repairing fatigue crack with laser so as to improve resource utilization rate. However, the effect of laser repair may be influenced by the instability of laser treatment. To investigate the addition of nanocomposites on the laser repairing effect, fatigue test under uniaxial tension was carried out

2. Probabilistic analysis of stress intensity factor (SIF) and degree of bending (DoB) in axially loaded tubular K-joints of offshore structures
Abstract The stress intensity factor (SIF) and the degree of bending (DoB) are among the crucial parameters in evaluating the fatigue reliability of offshore tubular joints based on the fracture mechanics (FM) approach. The value of SIF is a function of the crack size, nominal stress, and two modifying coefficients known as the crack shape factor (Yc) and ge

3. Towards a methodology for the practical applications of the EIFS (Equivalent Initial Flaw Size) concept
This work intends to introduce a probabilistic approach for the crack propagation analysis. It presents a methodology that is based on the distribution of the initial flaw size a0. Departing from fatigue test results for specific structural components, an estimation of the initial flaw distribution is obtained, and from this distribution it becomes possible

4. Validação de conteúdo das características definidoras do diagnóstico de enfermagem fadiga no paciente oncológico
Nursing has increased its know how and qualified its care by utilizing the Nursing Care System (NCS). As a part of the NCS, Nursing Diagnosis (ND) are the basis for the nursing care planning. In oncology, besides evidencing the problems experienced by the patients with cancer, the NDs can improve their quality of life starting from appropriate interventions

5. Fadigue reliability analusis : case study automotive suspension control arm / Analise de confiabilidade em fadiga : estudo de caso : braço de controle de suspensão automotiva
This dissertation aims at describing a procedure for approval of a suspension control arm subjected to high-cycle fatigue and, simultaneously, at proposing a validation alternative method based on reliability concepts and statistical theories. In that manner, the research provides not only an assessment of the procedure followed by the manufacturer, but also

6. Probabilistic analysis of durability applied to semi-trailer tank vehicle. / Análise probabilística de durabilidade aplicada a veículos de carga rodoviária.
Em projetos de veículos, prever adequadamente a durabilidade de um componente estrutural é vital para a redução de custos assim como para se estipular prazos de garantia e de manutenção. Por outro lado, em diversas situações, tal previsão é difícil, pois inúmeros parâmetros não estão sob controle preciso do projetista, dentre eles os mais rele
