Apparent modulus of elasticity of dental amalgams.
The modulus of elasticity of dental amalgam has been determined by analysis of creep data (OGLESBY ET AL, J Res Natl Bur Stan 72C: 203, 1968) and by ultrasonic methods (DICKSON and OGLESBY, J Dent Res 46: 1475, 1967; HALL ET AL, J Dent Res 52: 390, 1973) to be between 63,000 and 70,000 MN/m2. These values represent the instantaneous elastic compliance term when dental amalgam is treated as a vi...
متن کاملdeterminants of modulus of rupture and modulus of elasticity of particleboards on the basis of data base
the moe and mor are controlled by production variables of particleboard process. now, the basic question is which of the particleboard variables is effective on bending strength property? 13 variables of internal scientific resources were measured with 100 repeats. the study steps include the following; liner regression or stepwise, genetic algorithm, and artificial neural network. the number o...
متن کاملDifferences in Dynamic Modulus of Elasticity Determined by Three Vibration Methods and Their Relationship with Static Modulus of Elasticity
Dynamic modulus of elasticity was determined in clearwood samples of eight tropical hardwood species using longitudinal vibrations, flexural vibration and ultrasonic transit-time methods. These samples were subsequently subjected to three point static bending test to determine static modulus of elasticity and modulus of rupture. Acoustic velocity and wood density were found to be independent pa...
متن کاملDistinct Young's modulus of nanostructured materials in comparison with nanocrystals.
Young's modulus (Y) of nanostructured materials (NSs) free of porosity is modeled with regard to the coordination number imperfection at grain boundaries. In light of it, Y of NSs is suppressed substantially in the whole solid temperature range, differing from the case of nanocrystals (NCs) where Y is enhanced at lower temperature (T) but weakened at higher T. It is found that, similar to NCs, ...
متن کاملHardness and modulus of elasticity of primary and permanent teeth after wear against different dental materials
OBJECTIVES The purpose of this study was to determine the Young's modulus and the hardness of deciduous and permanent teeth following wear challenges using different dental materials. MATERIALS AND METHODS Wear challenges were performed against four dental materials: A resin-based fissure sealant (Fluoroshield(®)), a glass ionomer based fissure sealant (Vitremer(®)), and two microhybrid compo...
