Avaliação do teor dos aditivos estabilizantes e das propriedades mecânicas em compostos elastoméricos para lateral de pneu de passeio submetidos ao envelhecimento natural e acelerado
(2015-02-11)
This study aims at analysing the ideal rate of two stabilizers in elastomeric compounds, used in tires that require a long-term performance, submitted to different kinds of aging. The resistance to the aging can be achieved ...
Crescimento de trinca de fadiga no aço SAE 4140 sujeito à vibração forçada
(2015-10-26)
Fatigue is a common cause of failures in mechanical components and metal structures when subjected to dynamic loads, caused by the growth of a crack, with the so-called Paris’ law the main model for crack propagation. This ...

(2015-02-23)
The generation of waste, in general, can bring many environment issues due to their improper disposal, making necessary to search for alternative methods for handling, treatment and final disposal of them. The Brazilian ...
Análise da qualidade superficial no fresamento de aço P20 com diferentes tratamentos de ferramentas e condições de lubrirrefrigerantes
(2016-12-20)
This work studied the effect of edge preparation and its interaction with minimum quantity of lubricant (MQL) application over the surface integrity of the workpiece and wear in milling. The necessity of high productivity ...
Influência do metal de adição e da energia de soldagem na microestrutura e resistência à fadiga de juntas soldadas de aço de alta resistência e baixa liga DIN S700MC
(2017-05-10)
High strength and low alloy steels (HSLA) are attractive alternative in structural applications. Due to the low carbon and alloying elements (Ni, V and Ti) contents, HSLA steels show good levels of toughness and mechanical ...
