Efeito do tratamento da microgeometria de brocas helicoidais de metal-duro sobre a integridade superficial dos furos
(2014-07-10)
This work studied the effect of the meso and microgeometry of drills treatment on the surface integrity. The drilling process presents characteristics that render it a unique process under the thermal and mechanical ...
Influência do comportamento dinâmico em juntas do tipo "k" em estruturas reticuladas planas
(2015-10-26)
This thesis presents the study of plane frame structures, also called trusses. The great demand of construction, and projects increasingly bold motivated this research. Three models lattices were performed in order to ...
Efeitos do corte por laser sobre a integridade superficial de um aço médio carbono
(2015-02-11)
A condition of the manufacturing process is the need to get processed parts, characterized by good quality surface finish, low roughness and the conservation of its metallurgical properties. These conditions have motivated ...
Análise estática e dinâmica de pórticos espaciais com incerteza no carregamento utilizando o método de elementos finitos
(2015-11-23)
In this thesis, static and dynamic analysis of elastic space frames with regime uncertainty in loading using the finite element method (FEM) are described. A structural approach to the dynamic problem of forced vibrations ...
Avaliação dos parâmetros que influenciam nas alterações dimensionais e nas tensões residuais do polipropileno moldado por injeção
(2018-10-17)
The final quality of the injection molded polymer products can be compromised due to the occurrence of residual stresses from the molding process, which can generate shrinkage and warpage, altering the final product ...
