1. Finite element computational development for thermo-mechanical analysis of plane steel structures exposed to fire
Abstract This article presents a numerical formulation based on finite element procedures for application in nonlinear thermo-mechanical analyses of steel planar structures under fire condition. The mechanical properties of structural elements degrade when subjected to high temperatures, resulting in significant reductions in strength and stiffness. Under th

3. Preparation of organoclays appropriated and development of plasticized pvc nanocomposites / Preparação de argilas organofílicas para o desenvolvimento de nanocompósitos a partir de compostos de PVC plastificado
Nanocomposites of Plasticized PVC with organoclays have a large potential to improve the thermal resistance of PVC as well as its flame retardancy. However, a great problem in the production of PVC nanocomposites is the decomposition of conventional organic ammonium salts incorporated on the clay which can catalyze PVC degradation and lead to deterioration o

4. Modelado numérico del proceso de soldadura por fricción agitación en aceros inoxidables
In this work the friction stir welding (FSW) process of stainless steel probes is modeled by a general propose finite element program, reproducing both thermal and material flow distribution. In the FSW process the equipment consist essentially of a rotating tool, which travel along the joint of two restricted plates. The union results from the frictional he

5. Modelagem do comportamento termo-mecânico transiente de estruturas de materiais compósitos pela teoria de volumes finitos
The advance of the materials science has motivated the advent of composite materials with different characteristics that assure high performance thermo-mechanical, such as the advanced fiber reinforced composites and those that present a gradual variation in its microstructure. Nowadays, many computational models and analytical methods are being employed for

6. WEATHER-RELATED GEO-HAZARD ASSESSMENT MODEL FOR RAILWAY EMBANKMENT STABILITY
The primary objective of this thesis is to develop a model for quantification of weather-related railway embankments hazards. The model for quantification of embankment hazards constitutes an essential component of a decision support system that is required for the management of railway embankment hazards. A model for the deterministic and probabilistic asse

7. On the numerical simulation of machining processes
Numerical simulation of machining processes can be traced back to the early seventies when finite element models for continuous chip formation were proposed. The advent of fast computers and development of new techniques to model large plastic deformations have favoured machining simulation. Relevant aspects of finite element simulation of machining processe
