The most important item when indicating the mechanical properties of offshore elastomeric bearings is shear modulus, and method measuring this shown in EN 1337-3, a regulation related to bearings. In work, we conducted an experimental numerical study on bearing find its modulus. Shear modulus tests were according procedure specified 1337-3 Annex F, while simulations performed using finite eleme...

OBJECTIVE To investigate a potential relationship between degree of stretching and resulting permanent deformation of elastomeric chains (ECs) as well as whether or not stretching time has any bearing on the degree of permanent deformation. METHODS Five-module segments of closed elastomeric chains manufactured by 3M Unitek were stretched to 10-100% of their original length in devices especial...

Abstract Improper disposal and accumulation of waste tire rubbers have posed a serious threat to the development circular economy, sustainable environment, human health. In light drawback current management tires, recycling transformation reclaimed rubber (RR) into valuable end products has received significant attention from industries academic field. Herein, we propose facile method reuse RR ...

an ideal orthodontic force system should exert continuous light force. thus, many efforts have been made to improve the memory characteristics of elastomeric chains. the aim of this study was to compare elastomeric chains (ecs) claimed by their manufacturers to offer high memory with traditional ones according to their force-extension diagrams.in this in-vitro study, ecs were divided into six g...

Due to the technical evolution of tires, currently most automotive tires do not have an inner tube. However, truck, motorcycle and bicycle still use with tubes, mostly made synthetic elastomeric material, which guarantees good potential for air restriction or longer periods tire pressure failure. This work aims study changes in mechanical properties a truck tire, after its exposure gamma rays, ...

PROPOSITION The purpose of this study was to evaluate in vitro the color changes of esthetic orthodontic elastomeric ligatures of different shades when exposed to four food colorings commonly found in the diet of patients. MATERIALS AND METHODS The sample consisted of esthetic orthodontic elastomeric ligatures in the colors pearl, pearl blue, pearl white and colorless, which were immersed for...

Background and Objectives: Cold water disinfection can damage the elastomeric material, cross contamination in handling elastomeric ligatures is a serious concern in the orthodontic office. In addition, elastomeric strips with enough ligatures for both arches of a single patient are produced by most manufacturers. Thus, cross -contamination can occur in remaining ligatures if an entire strip is...

The bearing plates used in plate load test for highway engineering are typically rigid. However, due to limitations obtaining the accurate distribution of compressive stress at bottom plate, there is often a significant deviation between measured subgrade resilient modulus and actual condition. To address this issue, flexible can be obtain more modulus. In study, we use variance degree mean qua...
