Pluviosidade crítica e aspectos agravantes de deslizamentos nas encostas da Cidade do Rio de Janeiro - período de 1998 a 2002 Ver

This study analyzes the effects of rainfall in the landslides in the city of Rio de Janeiro for the years of 1998 to 2002 and the results compared to those from the years of 2010 to 2012. These results show that the rainfall events are the predominant...

Aplicação de métodos experimentais alternativos para avaliação da retardância à chama em madeiras Ver

This work evaluates experimentally the flame retardancy of woods by means of test methods not adopted by the current Brazilian flammability classification of materials. So, a phosphorus-based flame retardant was applied on the surface of samples of E. dunnii, P. elliottii and MDF. ...

Relações empíricas para estimativa da resistência ao arrancamento de ancoragens Ver

This work presents a database created after an extensive research in the national literature, from the reporting on tests with information on site, soil type, anchorage type, test methods and pullout resistance methods of determination. The database consisted of 445 tests, of which ...

Análise de problemas conjugados em microssistemas térmicos com múltiplas correntes e geometrias complexas via transformação integral Ver

A numerical-analytical hybrid solution is presented through the Generalized Integral Transformation Technique (GITT) using a single-domain reformulation with a total transformation scheme for problems of conjugated heat transfer in thermal micro-systems with flows of immiscible fluids in direct contact,&#x...

Modelagem constitutiva de ligas magnéticas com memória de forma Ver

Magnetic shape memory alloys (MSMAs) have the ability to deform under thermo, mechanical or magnetic fields actuation, offering the option of contactless control for high excitation frequencies. These characteristics make MSMAs a potential candidate for a new generation of sensors and actuat...

Análise numérica de cravação de estacas torpedo modeladas por integral de pressões Ver

In deep-water offshore oil exploration, the mooring foundations are usually submitted to high loads in a soil that is, usually, extremely soft. To circumvent this problem, torpedo anchor is frequently used to fix the mooring line on seabed. In this context, this paper presents ...
