On the use of finite elements with a high aspect ratio for modeling cracks in quasi-brittle materials
(2016-03-01)
A new technique for modeling cracks in quasi-brittle materials based on the use of interface solid finite elements is presented. This strategy named mesh fragmentation technique consists in introducing sets of standard ...
Thermo-optics parameters measurements in photorefractive sillenite Bi(12)SiO(20) crystals by thermal lens technique
(NATL INST OPTOELECTRONICS, 2011)
The present work reports on the thermo-optical properties of photorefractive sillenite Bi(12)SiO(20) (BSO) crystals obtained by applying the Thermal Lens Spectrometry technique (TLS). This crystals presents one high ...
Effect of disinfectant agents on dimensional stability of elastomeric impression materials.
(1999-05-01)
STATEMENT OF PROBLEM: Difficulties in sterilizing impressions by traditional methods have led to chemical disinfection as an alternative, and some studies have shown that disinfectants may adversely affect impressions. ...
