context, few published papers ...
Avaliação da confiabilidade de pilares curtos em concreto armado projetados segundo a NBR 6118:2003
(Universidade Federal de Minas GeraisUFMG, 2006-10-16)
Several studies have demonstrated the economical feasibility of the utilization of highstrength concrete (HSC) in the lower columns of high- and medium-rise buildings. Several international codes have already updated their ...
Evaluation of shear bond strength at the interface of two porcelains and pure titanium injected into the casting mold at three different temperatures
(Mosby, Inc, 2004-06-01)
Statement of problem. Titanium has physical and mechanical properties, which have led to its increased use in dental prostheses despite casting difficulties due to high melting point and formation of oxide layers which ...
Opaque Layer Firing Temperature and Aging Effect on the Flexural Strength of Ceramic Fused to Cobalt-Chromium Alloy
(Wiley-Blackwell, 2010-08-01)
Purpose: To evaluate the effect of the opaque layer firing temperature and mechanical and thermal cycling on the flexural strength of a ceramic fused to commercial cobalt-chromium alloy (Co-Cr). The hypotheses were that ...
