1. PREDICTION OF COAL SLURRY PIPELINE TRANSPORTATION GRADING REDUCTION AND ITS INFLUENCE ON PIPE TRANSPORTATION PARAMETERS
Abstract Coal slurry pipe, being a new type of energy transportation mode, changes of the particle composition and the effect on other parameters are worth studying. Comparison of ring tube test measured data and batch grinding model simulation data shows that batch grinding model can predict the coal particle gradation to a certain extent. The effect of col

2. Multistage Deep Drawing with Ironing of Al-killed AISI 1040 Graded Medium Carbon Steel: a Parametric Study
Analysis of multistage deep drawing with ironing was made while manufacturing of cups from 12 mm thick, 60 mm diameter circular blanks of Al-killed AISI 1040 graded medium carbon steel. Quality requirements of the steel in heat treated condition were examined in terms of tensile properties, formability characteristics, and formability limit diagram. Drawabil

3. Microextrusão de peças aplicadas a materiais ferrosos e não ferrosos
This thesis presents the study about microforming, in this case microextrusion of the four different materials, an SAE 1020 steel, an AISI 304 stainless steel, an AA6531 aluminum and a C34000 brass. To evaluate the size effect about microextrusion process, two sizes of specimens were used, with a ¿ 4 mm and another with ¿ 1 mm. For each size of specimen, t

4. Análise da influência de parâmetros do processo de trefilação de barras cilíndricas de aço AISI 1045 via simulação numérica computacional / Title: parameters analysis of the drawing of AISI 1045 steel rods via FEM
This paper aims to analyze the drawing process using simulation and evaluate the influence of process variables such as lubricant (friction coefficient) and angle of die as well as verify the effectiveness of simulation to preview the drawing force, temperature and residual stresses. Experimental work was carried out involving the determination of friction c

5. Evaluation of two commercially-available lubricants by means of ring test to AA 6061 F aluminum alloys
This paper shows friction results obtained through compression ring tests for two commercially-available lubricants (i.e., Oildag and Deltaforge) applied in the hot forging of aluminum alloys. The experiments were performed with AA 6061 F aluminum alloy samples with the goal of observing the behavior of each lubricant in several conditions of temperature (20

6. Interface strength between geomembranes and soils by ring shear test / Resistência de Interface entre geomembranas e solos através do ensaio de Ring Shear
This paper deals with the shear strength in the geomembrane-soil interfaces used in landfill and waste pond liners. Modified ring shear tests were carried out using sandy and clayey soils, in dry and saturated conditions. The tests were performed using a coarse to medium graded sand and a clayey soil from a sanitary landfill in Piracicaba - SP. In this work,

7. CaracterizaÃÃo geotÃcnica de um solo de calcÃrio da Encosta Continental/PE-18, Paulista-PE, com Ãnfase na resistÃncia ao cisalhamento
The main objective of this dissertation is the study of the geotechnical characteristics, of the layer of calcareous silty clay involved in the landslides that occurred in an area situated in highway BR 101 North, PE 18, in the industrial district of Paulista, with emphasis in its shear strength. A slope with instability problems between highway PE- 18 and t

8. Estudo do processo isotermico de forjamento de precisão, atraves do metodo de elementos finitos
o estado da arte, no forjamento, aponta para o forjamento de precisão. Este tipo tem por meta a produção de forjados com urna qualidade de acabamento que reduza, em parte ou integralmente, as operações secundárias de acabamento. Para atingir este objetivo o projeto de urna peça forjada exige o abandono do método tradicional de tentativa e erro. O uso
